Software Activation
Catalyst 3750-E and 3560-E switches run the universal software image that has the Cisco IOS code for
multiple feature sets. To enable a specific feature set, you must use the software activation feature to
install the software license for that feature set. With software activation, you can
•
Generate a software license.
•
Install the software license on your switch.
•
Enable a feature set.
•
Upgrade a feature set.
Beginning with Cisco IOS Release 12.2(46)SE, the switches support these features:
Note
•
Temporary software licenses
•
Rehosting a software license
•
Cisco License Call Home
Catalyst 3750 and 3560 switches run feature-specific software releases and do not support software
activation.
Catalyst 3750-E and 3560-E switches support either the noncryptographic or the cryptographic universal
software image.

Understanding Software Licenses
A software license applies only to a specific feature set. A Catalyst 3750-E or 3560-E switch can have
more than one software license, but you can enable only one license at a time.
By default, if more than one software license is installed on the switch, this hierarchy determines the
first software license to locate in the flash memory and to install:
1.
Advanced IP services
2.
IP services
3.
IP base
If all three licenses are installed on the switch, the switch uses the highest license level, the advanced IP
services feature set.
Cisco Software Activation and Compatibility Document
OL-11445-03

Software Activation
To run the IP base feature set on the switch:
•
If the switch is running a software image earlier than Cisco IOS 12.2(46)SE, remove the IP services
and advanced IP services licenses from the switch, save the switch running configuration, and reload
the switch.
•
If the switch is running Cisco IOS Release 12.2(46)SE or later, enter the license boot level ipbase
privileged EXEC command, save the switch running configuration, and reload the switch.
The switch supports permanent and temporary software licenses.
The permanent license is node-locked because it is bound to the unique device identifier (UDI) of the
switch and can only be used on that switch. When you order a new switch, the switch has the permanent
software license that you selected.
A temporary software license is limited to a usage period and can be one of these types:
•
Embedded evaluation license in the software image
The evaluation license is node-locked and is valid for 60 days.
You can use this license to minimize network downtime if a switch fails and the replacement switch
does not have the same software license. You can also use the license to evaluate a feature set on the
switch.
•
Extension license
You can get this license from Cisco TAC. It is node-locked and is valid for 60 days.
•
Grace-period license
During the rehost process, when the license on a switch is revoked and transferred to another switch,
this license is automatically installed to prevent network disruption. It is valid for 60 days.
After the usage period expires, the switch continues to use the temporary software license until it is
restarted. Before it restarts, warning messages state the switch is running the feature set without a valid
license. After the switch restarts, the switch uses a valid software license based on the previously
described hierarchy. If the switch does not have a valid license, it uses the IP base software license. For
examples of using a temporary license, see the “Changing the Software License on the Switch” section
on page 21.

feature module at this URL:

Getting Software Licenses
Use one of these methods to get a software license:
•
When ordering a switch, specify the software image and feature set to be installed.
•
If you want your switch to run a different feature set, purchase the software license for that feature
set, and get a product activation key (PAK). Use one of these processes to install the software
license:
– Use the Cisco License Manager.
a. Enter the PAK in the GUI.
b. The Cisco License Manager installs the software license for you.
– Use the Cisco Product License Registration Portal.
a. To register your software license by using the PAK, go to www.cisco.com/go/license.
b. The software license file is e-mailed to you. We recommend that you copy the file on your
switch flash memory.
c. Install the software license on the switch by using Cisco IOS CLI commands.
– Use the Cisco License Call Home feature.
•
Rehost the software license.
– Revoke a license from a source switch, and transfer it to a destination switch.
– We recommend that you use the Cisco License Manager when rehosting a software license.
– You cannot rehost an evaluation software license.
•
Request that the software license file be remailed from the Cisco Product License Registration Portal
if the file is corrupted.
Cisco Product License Registration Portal
Follow these steps to get a PAK and a software license for a feature set:
Step 1
After deciding on the feature set that you want, contact Cisco TAC to request a PAK.
Step 2
After you purchase the software license, the PAK is sent to you.

Changing the Software License on the Switch
These are valid rehost and upgrade scenarios:
•
If your switch is running the IP base feature set, you cannot rehost the IP base license, but you can
upgrade to the IP services feature set by getting the IP services software license. After you restart
the switch, it runs the IP services feature set.
•
If your switch is running the IP services feature set and you rehost the IP services software license
to another switch, the switch continues to run the IP services grace-period license. After the
grace-period license expires, messages appear about the switch running the IP services feature set
without a valid license. After you restart the switch, the switch runs the IP base feature set.
Cisco Software Activation and Compatibility Document

Feature Compatibility
You can upgrade the software license to the advanced IP services license. The switch continues to
run the IP services feature set. After the switch restarts, it runs the advanced IP services feature set.
•
If your switch is running the IP services feature set, you can enable the advanced IP services
evaluation software license to try the advanced IP services feature set. If you decide to buy the
advanced IP services software license, get the upgrade PAK, and install it on the switch. The
software license automatically replaces the evaluation license, and the switch continues to run the
advanced IP services feature set. You do not need to restart the switch.
Activating Software in Mixed Hardware Stacks
Although the Catalyst 3750 switch does not support software activation, the Catalyst 3750 master in a
mixed hardware stack supports the software license administration and management functions.
We recommend that all stack members run Cisco IOS Release 12.2(35)SE or later. The stack members
are then fully compatible, and the interface-specific settings of the stack master are saved if the stack
master is replaced without saving the running configuration to the startup configuration.
When you upgrade the Catalyst 3750-E universal software image in the stack, all stack members
automatically get the copies of the Catalyst 3750-E software image and the Catalyst 3750
feature-specific image. During the upgrade, these actions occur automatically:
•
On a Catalyst 3750-E member, the software images are copied to the switch, and the switch enables
the appropriate feature set.
•
On a Catalyst 3750 member, the software images are copied to the switch, and the switch uses the
feature-specific image that corresponds with the enabled feature set on the Catalyst 3750-E member.
Make sure that the Catalyst 3750 members have enough flash memory to store both images. For instance,
only Catalyst 3750 switches with 32 MB of flash memory (such as the Catalyst 3750G-48TS switch)
have enough. If a member switch does not have enough flash memory, the upgrade process stops, and an
error message appears.
When archiving (uploading and downloading) software images in a mixed hardware stack, you can
specify multiple software images. For example, to download the two image files from the TFTP server
to the switch, enter the archive download-sw/directory tftp://10.1.1.10/
c3750-ipservices-tar.122-35.SE1.tar c3750e-universal-tar.122-35.SE2.tar privileged EXEC
command.
For more information about working with software images, see the “Working with Software Images”
section in the Catalyst 3750-E and 3750 switch software configuration guides and the archive
commands in the Catalyst 3750-E and 3750 switch command references.
Feature Compatibility
Unless otherwise noted, the features on Catalyst 3750-E, 3750, 3560-E, and 3560 switches are the same

When fallback bridging is
enabled, the switch can use all of

Mixed Hardware Stacks
Because of collisions, the switch
might not be able to store a few
MAC address table entries even
if it has free hardware memory.
HSRP
The switch supports up to
32 unique HSRP groups.
When you specify the same
group number for multiple
VLANs or router interfaces, the
switch creates one hardware
entry per HSRP group number.
The switch supports up to
32 HSRP groups regardless of
the group number.
When you specify the same
group number for multiple
VLANs or router interfaces, the
switch creates a hardware entry
for each VLAN or interface.
Some HSRP groups might have
the same group number
associated with different VLANs
or router interfaces.
A Catalyst 3750-E member
behaves like a Catalyst 3750
member. If the Catalyst 3750-E
member has an HSRP
configuration that the
Catalyst 3750 member does not
support, the stack discards the
HSRP configuration.
If you add a Catalyst 3750 switch
as a member in a
Catalyst 3750-E-only stack, the
switch enters mismatch mode.

redirect is not supported for host
routes or for summarized routes

When configuring equal-cost
routes, the router might choose
different paths, depending on the
ingress switch.
A multicast packet is unmatched
when the destination IPv6
address does not match the
destination MAC address. The
unmatched multicast packet is
forwarded in hardware.
The unmatched multicast packet
is forwarded in software, which
might cause the high CPU
utilization.
If a Catalyst 3750 member
receives an unmatched multicast
packet, the switch forwards the
packet in software.

Mixed Hardware Stacks
—
—
The SSH12 connection to the
switch stack can be lost if the
Catalyst 3750-E master running
the cryptographic software
image and the IP base or IP
services feature set fails and one
of these actions occur:
•
The stack master is replaced
by a Catalyst 3750-E
member running the
noncryptographic image and
the IP base or IP services
feature set.
•
The master is replaced by a
Catalyst 3750 switch
running the
noncryptographic image and
the IP base or IP services
image.
We recommend that a stack
master run the cryptographic
image and the IP base or IP
services feature set.
Switch memory
usage
The switch uses hardware
memory to store unicast routes,
MAC addresses, ACLs, and
other feature information and to
provide the SDM templates that
allocate memory resources,
depending on how the switch is
used.
The switch uses TCAM to store —
unicast routes, MAC addresses,
ACLs, and other feature
information and to provide the
SDM templates that allocate
memory resources, depending on
how the switch is used.
Because of collisions, in some
cases, the switch cannot store a
few MAC address table entries
even if it has free hardware
memory.
System MTU
You can configure the system
jumbo MTU and the system
routing MTU values on the
switch ports.
The switch allows multicast
routing of jumbo frames.
You can configure the system
MTU, the system jumbo MTU,
and the system routing MTU
values on the switch ports.
For information about
configuring the system MTU
values on stack members, see the
“Configuring the System MTU”
section in the Catalyst 3750-E
and 3560-E Switch Software
Configuration Guide.

Configuration Guidelines in Mixed Hardware Switch Stacks
This document describes the interactions of Catalyst 3750-E and 3750 members in a mixed hardware
switch stack. For more information about switch stacks, see the Catalyst 3750-E and 3560-E Switch
Software Configuration Guide and the Catalyst 3750 Switch Software Configuration Guide on
Cisco.com.
Follow these guidelines when configuring mixed hardware stacks:
•
We recommend that a Catalyst 3750-E switch be the stack master.
•
We recommend that all stack members run Cisco IOS Release 12.2(35)SE or later to ensure
compatibility between the stack members. For more information, see these sections in the
“Managing Switch Stacks” chapter in the Catalyst 3750-E and 3750 software configuration guides:
– “Switch Stack Software Compatibility Requirements” section
– “Stack Protocol Version Compatibility” section
– “Major Version Number Compatibility Among Switches” section
– “Minor Version Number Compatibility Among Switches” section
The stack members in a mixed software stack use the automatic upgrade (auto-upgrade) and the
automatic advise (auto-advise) processes to detect mismatched software and to try to upgrade a
member in version-mismatch (VM) mode.
•
We recommend assigning the highest priority value to the switch that you prefer to be the stack
master. This ensures that the switch is re-elected as stack master if a re-election occurs. In a mixed
hardware stack, assign the highest priority value to a Catalyst 3750-E switch.
•
When configuring system-wide features, see the “Feature Compatibility” section on page 22 and the
“Additional Considerations for System-Wide Configuration on Switch Stacks” section in the
“Managing Switch Stacks” chapter in the Catalyst 3750-E and Catalyst 3750 switch software
configuration guides.
•
Hardware compatibility and SDM mismatch mode
– The Catalyst 3750-E switch supports only the desktop Switch Database Management (SDM)
templates. The Catalyst 3750 switch supports either the desktop or aggregator SDM templates.
– All stack members use the SDM template configured on the stack master. In a mixed hardware
stack:
Only the switches using the same desktop SDM template as the stack master can be stack
members. All other switches trying to join this switch stack enter SDM-mismatch mode.
If a Catalyst 3750 stack master is using an aggregator template, Catalyst 3750-E switches
cannot be stack members. Only Catalyst 3750 aggregator switches can be stack members.

You can connect to the stack master by using one of these methods:
– You can connect a terminal or PC to the stack master through the console ports of one or more
stack members.
– You can connect a PC to the stack master through the Ethernet management ports of one or more
Catalyst 3750-E stack members. If the stack master is a Catalyst 3750 switch and at least one
stack member is a Catalyst 3750-E switch, you can manage the stack through the PC.
