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:

•Temporary software licenses

•Rehosting a software license

•Cisco License Call Home

---

Note 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.

Beginning with Cisco IOS Release 15.0(2)SE1, the switches support right-to-use licensing. The right-to-use licensing model is an easier method to upgrade or downgrade from one license level to another without having to interact with the Cisco Product License Registration portal. For details, see "Managing Software Licenses Using Right-To-Use Features" section.

Feature Sets

Catalyst 3750-E and 3560-E switches support these feature sets:

•IP base

•IP services

The software licenses are not affected by Cisco IOS software upgrades.

Catalyst 3750-E and 3560-E switches are backward-compatible with Catalyst 3750 and 3560 switches. For detailed information about the feature compatibility between the switches, see the "Feature Compatibility" section.

Table 1 describes the feature sets supported on Catalyst 3750-E and 3560-E switches and the software images supported on Catalyst 3750 and 3560 switches.

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. IP services

2. IP base

If all the licenses are installed on the switch, the switch uses the highest license level, the IP services feature set.

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 license 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 that 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.

For more information about software licenses, see the Cisco Software Activation Conceptual Overview feature module at this URL:

http://www.cisco.com/en/US/docs/ios/csa/configuration/guide/csa_overview.html

Getting and Installing Software Licenses

This section has these procedures:

•Getting Software Licenses

•Installing Software Licenses by Using Cisco License Manager

•Installing Software Licenses Using Cisco License Call Home

•Installing Software Licenses Using the Cisco IOS CLI

•Rehosting Software Licenses Using Cisco License Manager

•Rehosting Software Licenses Using Cisco License Call Home

•Requesting that Software Licenses be Remailed Using Cisco License Call Home

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.

Step 3 Go to the Cisco Product License Registration Portal at www.cisco.com/go/license.

Step 4 Use the PAK and the switch UDI to create a software license file.

Step 5 The software license file is e-mailed to you.

---

Cisco License Manager

With Cisco License Manager, you can perform these tasks from one application:

•Automatically discover software licenses on your switches

•Install software licenses

•Track the software license status in your network

Use the Cisco License Manager GUI to perform all of these licensing tasks. You can also use the Cisco License Manager application programming interface (API) to write programs for your specific licensing tasks.

Cisco License Manager runs on Windows XP and uses Java to connect to Cisco.com and to Cisco devices. For information about downloading the free Cisco License Manager Client and Server applications or about ordering the optional Cisco License Manager software development kit (SDK), go to this URL:

Installing Software Licenses by Using Cisco License Manager

Use Cisco License Manager to install and manage software licenses on the switch.

Follow these guidelines when using Cisco License Manager:

•Cisco License Manager only runs on a server with Windows XP.

•Firewalls are not allowed between the Cisco License Manager server and a GUI client.

•For device notification to be successful, ensure that the Cisco License Manager hostname exists in the Domain Name Service (DNS) or that the device has the Cisco License Manager hostname and IP address configured to receive messages.

•Configure your switch to allow Cisco License Manager to manage software licenses by using the ip http server privileged EXEC command and the license agent default authenticate none global configuration command. For a summary of these commands, see the Getting Started with Cisco License Manager on Windows XP guide. For detailed instructions about enabling Cisco License Agent on your device, see the Cisco License Agent documentation.

•Make sure that there is a valid connection from the Cisco License Manager server to Cisco.com.

–In Cisco IOS Release 12.2(46)SE or later, if the software license is in use (active):

a. Enter the license boot level license-level global configuration command to specify a license level different from the current one.

b. Restart the switch to enable new software license.

c. Enter the license clear license-level [switch switch-num] privileged EXEC command to remove previous software license.

–In Cisco IOS Release 12.2(46)SE or later, enter the license clear license-level [switch switch-num] privileged EXEC command to remove an unused software license.

•Backing up and saving software license information—Enter the license save {credential url | url} privileged EXEC command.

–Use the credential url parameter to save the device credential information and to specify the URL to which the information is saved.

–Use the url parameter to specify the URL of the software image.

•Recovering from a corrupt license:

–Use the Cisco License Call Home feature to request that the software license file be remailed.

–Use the Cisco IOS CLI commands to re-install an uncorrupted version of the license on the switch.

Managing Software Licenses Using Right-To-Use Features

If you want to upgrade or downgrade from one license level to another, or remove the license from one switch and install on another, we recommend that you use the right-to-use (RTU) license instead of the node-locked license.

•Overview of RTU License

•Benefits of an RTU License

•Guidelines for the RTU License Model

•Applying an RTU License on a Switch

•Activating the RTU License on a Switch

•Deactivating the RTU License on a Switch

Overview of RTU License

Right-to-use (RTU) is a new licensing system that allows you to install or remove a license on your switch without interacting with the Cisco Product License Registration portal. Previously, when you upgraded from one license level to another (for example, from IP Base to IP Services), you visited http://www.cisco.com/go/license, obtained the desired license using your device's PAK, and then applied the license on your device. For details of the Cisco IOS activation process, see the Configuring the Cisco IOS Software Activation Feature guide at this URL: http://www.cisco.com/en/US/docs/ios/csa/configuration/guide/csa_commands.html

With the new RTU license, you can instantly install a license on any supported switch by using CLI commands without obtaining a license through the Cisco Product License Registration Portal. You can do the following tasks using the RTU license:

•Upgrade from a lower license to a higher license.

•Downgrade from a higher license to a lower license.

•Move licenses from one switch to another by deactivating the license on the first switch and activating on the second.

Benefits of an RTU License

RTU licenses provide the following key benefits:

•They are not associated with specific switches. With the node-locked license model, a license is applicable to a particular switch UID. Therefore, to activate a license on a new switch, you had to obtain a new license for the new switch's UID. RTU licenses are not specific to switch UIDs and can be freely transferred from one switch to another.

•They can be instantly activated on any supported switch. With the node-locked license model, you open the Cisco Product License Registration Portal to obtain a license for a new switch that you purchase or an RMA switch that you need to replace. This process is often cumbersome and lengthy, and applying the license on the new switch is an error-prone activity. With RTU licenses, you can apply a license on a switch and activate it immediately.

•They can be applied without requiring an Internet connection. With the node-locked license model, you need to access an Internet connection to obtain a license for your device's UID. This may be difficult in some deployment scenarios where an Internet connection is not available. With RTU licenses, you can apply a supported license on any switch at any time without requiring an Internet connection to interact with the Cisco Product License Registration Portal.

Guidelines for the RTU License Model

•The RTU license model is based on mutual trust between you and Cisco. When you apply an RTU license, it is implied that you have first purchased the license from Cisco. This agreement is explained in detail in the EULA, which is displayed when you activate the license.

•The RTU license model does not replace the node-locked license model. Instead, it provides an easier method of upgrading or moving your switch's license. You can still use the node-locked license model if you choose to.

•In a switch stack, you can use multiple switches that have both licensing models. For example, you can configure a switch stack to use IP Services node-locked license on some switches and IP Services RTU license on other switches.

•RTU licenses are permanent licenses. Evaluation licenses are not supported in the RTU licensing model.

Applying an RTU License on a Switch

To apply an RTU license on a switch, follow these steps:

---

Step 1 Upgrade from one license level to another by using the Cisco sales ordering tool to purchase the license. You will receive an e-mail or paper confirmation that grants you permission to activate the license on your switch.

Step 2 Apply the license by entering the appropriate commands on your switch. If you are upgrading a license on a switch, enter the activation command to activate the higher license. If you are moving a license from one switch to another, enter the deactivation command on the first switch and the activation command on the second switch.

Step 3 Read and accept the End User License Agreement (EULA).

Step 4 Reboot the switch to boot with the highest available license.

---

Activating the RTU License on a Switch

To activate the RTU license on a switch, follow these steps beginning in privileged EXEC mode:

	Command	Purpose
Step 1	license right-to-use activate license-level	Activates a license on a switch.
Step 2	license right-to-use activate license-level acceptEULA	(Optional) Activates a license on a master or member switch and accepts the EULA automatically. This step may be required in situations where deployments are automated using install scripts.
Step 3	license right-to-use activate license-level switch switch-num	(Optional) Activates a license for a member switch on a switch stack.
Step 4	reload	Reboots the switch to boot with the highest available license.

Deactivating the RTU License on a Switch

To deactivate the RTU license on a switch follow these steps beginning in privileged EXEC mode:

	Command	Purpose
Step 1	license right-to-use deactivate license-level	Deactivates a license on a switch.
Step 2	license right-to-use activate license-level switch switch-num	(Optional) Deactivates a particular license for a member switch on a switch stack.
Step 3	reload	Reboots the switch to boot with the highest available license.

Displaying Software License Information

To display information about the software licenses on your switch, use one of these methods:

•Use Cisco License Manager to view license and device information. In the GUI, the discovery and polling features collect all the license and device information that appears in the Properties window. For detailed instructions, see the Cisco License Manager online help.

•Use the Cisco IOS privileged EXEC commands in Table 2.

In a mixed hardware stack, the show license udi command output shows only the Catalyst 3750-E UDIs because only those member switches support the software activation process. For example, in a mixed hardware stack with a Catalyst 3750 switch as the stack master and a Catalyst 3750-E switch as the stack member, this output appears when you enter the show switch privileged EXEC command on the Catalyst 3750 stack master:

Switch# show switch

Switch/Stack Mac Address : 0012.7f43.b680

*3       Master 0012.7f43.b680     1      0       Ready

When you enter the show license udi command on the Catalyst 3750 stack master, this output appears for all the stack members that support software activation:

Switch# show license udi

This is an example of output from the show license udi switch 1 command on the stack master, which shows that the UDI is for the local switch, switch 1:

Switch# show license udi switch 1

If you enter the show license udi switch 3 command on the stack master, this output appears for all of the stack members that support software activation. It is the same as the show license udi command output:

Switch# show license udi switch 3

If a mixed hardware stack has a Catalyst 3750 member switch, this is an example of output when you enter the show license udi command on any Catalyst 3750 member:

Switch# show license udi switch 5

Using TFTP to Install a Software License

After you get a software license file from the Cisco Product License Registration Portal, this example shows how to use TFTP to install the license on a switch:

Switch# copy tftp flash: 

Address or name of remote host [ ]? 10.0.0.1 

Source filename [ ]? license_name-ips 

Destination filename [license_name-ips]? 

Accessing tftp://172.20.244.138/r1fs-ips... 

Loading license_name-ips from 172.20.244.138 (via GigabitEthernet1/0/1): ! 

[OK - 1161 bytes] 

1161 bytes copied in 0.059 secs (19678 bytes/sec) 

If you enter the show flash: privileged EXEC command, the command output shows that the software license file is in the flash memory but that the feature set is not enabled.

Switch# license install flash: license_name-ips

Installing licenses from "flash: license_name-ips " 

Installing...Feature:ipservices...Successful:Supported

1/1 licenses were successfully installed 

0/1 licenses were existing licenses

0/1 licenses were failed to install

Switch# 

19:46:56: %IOS_LICENSE_IMAGE_APPLICATION-6-LICENSE_LEVEL: Next reboot level = ipservices 
and License = ipservices

After installing the license for the IP services feature set on the switch, you can enter the show version privileged EXEC command to display the software license information. In this example, the switch is currently running the IP base feature set.

Switch# show version

<output truncated>

License Level: ipbase   Type: Permanent

Next reboot license Level: ipservices

<output truncated>

Restart the switch to enable the IP services feature set.

Use the show version command to display the software license information after restarting the switch:

Switch# show version

<output truncated>

License Level: ipservices   

License Type: Permanent

Next reboot license Level: ipservices

<output truncated>

Using Cisco License Call Home to Rehost a Software License

This example shows show to revoke a software license from a source switch, Switch 2, and transfer it to a destination switch, Switch 3. Switch 2 and Switch 3 are members of a switch stack.

Before revoking the license from Switch 2, enter the show license udi privileged EXEC command to get the PID and UDI of Switch 3.

Switch# show license udi

Device#   PID                   SN              UDI

-----------------------------------------------------------------------------

Install the software license file on Switch 3, and restart the switch.

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.

•If your switch is running the IP base feature set, you can enable the IP services evaluation software license to try the IP services feature set. If you decide to buy the 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 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.

In a switch stack, you can use switches that have both licensing models. For example, you can configure a switch stack to use an IP Services node-locked license on some switches and an IP Services RTU license on other switches.

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 except for the information in this section.

Only the Catalyst 3750-E and 3560-E switches support these features:

•Power monitoring and power policing on Power over Ethernet (PoE) ports

•On-board failure logging (OBFL)

•Ethernet management ports

•Support for universal software images and the software activation feature.

•Full IPv6 prefix length for IPv6 ACLs

•Flow-based SPAN

•Enhanced Power over Ethernet to 20 W

Table 3 describes the feature behavior differences between the Catalyst 3750-E, 3750, 3560-E, and 3560 switches.

Table 3 Feature Behavior Differences 

Feature	Catalyst 3750-E and 3560-E Switches	Catalyst 3750 and 3560 Switches	Mixed Hardware Stacks
Fallback bridging	The switch stores the MAC addresses of the bridge group and of the VLAN associated with the SVI as two separate entries in the bridge-group MAC address table. When fallback bridging is enabled, the switch uses only half of the feature resources allowed by the configured SDM1 template to store MAC addresses. Because of collisions, the switch might not be able to store a few MAC address table entries even if it has free hardware memory.	The switch stores the MAC address of the bridge group and of the VLAN associated with the SVI as one entry in the bridge-group MAC address table. When fallback bridging is enabled, the switch can use all of the feature resources allowed by the configured SDM template.	A Catalyst 3750-E member behaves like a Catalyst 3750 member.
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.
IGMP	A multicast packet is unmatched when the destination IPv4 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 high CPU utilization.	If a Catalyst 3750 member receives an unmatched multicast packet, the switch forwards the packet in software. If a Catalyst 3750-E member receives an unmatched multicast packet, the switch forwards the packet in hardware.
IP multicast routing	A multicast packet is unmatched when the destination IPv4 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 high CPU utilization.	If a Catalyst 3750 member receives an unmatched multicast packet, the switch forwards the packet in software. If a Catalyst 3750-E member receives an unmatched multicast packet, the switch forwards the packet in hardware.
	You can configure the PIM2 version and enable the PIM mode on the Layer 3 interface on which multicast routing is enabled. When an IPv4 SDM template is enabled, the switch supports up to 64 PIM-enabled interfaces in hardware. When a dual IPv4 and IPv6 template is enabled, the switch supports up to 32 PIM-enabled interfaces in hardware.	For all SDM templates, the switch supports up to 128 PIM-enabled interfaces in hardware based on the TCAM3 .	—
IP unicast routing	On the switch or in a Catalyst-3750-E-only stack, you can configure 20 private VLANs and 105 PBR4 policies regardless of the number of configured VRFs5 (up to 26 VRFs). You can enable VRF on a private VLAN and the reverse.	On the switch or in a Catalyst 3750-only stack, these are the maximum numbers of VRFs, private VLANs, and PBR policies that can be configured: •When no VRFs are configured, you can configure 20 private VLANs and 105 PBR policies. •When up to 26 VRFs are configured, you can configure 20 private VLANs and 42 PBR policies. •If more than 42 PBR policies are configured, you cannot configure VRF. You cannot enable VRF on a private VLAN and the reverse.	The maximum numbers of VRFs, private VLANs, and PBR policies that can be configured on a mixed hardware stack is the same as those for a Catalyst 3750-only stack. A Catalyst 3750-E member behaves like a Catalyst 3750 member. After the stack restarts: •The member rejects the VRF configuration when VRF is enabled on a private VLAN. •If at least one VRF is configured, the member rejects the PBR policy configuration after 42 PBR policies is reached. The Catalyst 3750 switch goes into feature-mismatch mode when the switch tries to join a Catalyst 3750-E-only stack with one of these configurations: •Both VRF and private VLANs are enabled. •The VRF configuration has more than 42 configured policies. You must remove the stack VRF configuration so that the Catalyst 3750 switch can join the stack. The unsupported VRF configuration cannot be part of the provisioned configuration for the Catalyst 3750 switch.
	The switch has no limitations for ICMPv46 redirect.	The switch supports ICMPv4 redirect for routes with mask lengths less than 32 bits. ICMP redirect is not supported for host routes or for summarized routes with mask lengths greater than 32 bits.	—
	The switch has no limitations for unicast reverse path forwarding (unicast RPF).	The switch does not support unicast RPF.	You cannot configure unicast RPF on switches in a mixed hardware stack.
IPv6 ACLs	The switch supports the ahp and routing keywords in the deny (IPv6 access-list configuration) and the permit (IPv6 access-list configuration) commands. If a port or router ACL has ACEs7 with the ahp keyword, the routing keyword, or both, you can perform these tasks: •On a standalone switch or a Catalyst 3750-E-only stack –Apply the port ACL to a switch port. –Apply a router ACL to an SVI. –Modify the port or router ACL by adding the ahp keyword, the routing keyword, or both. •On a Catalyst 3750-E-only stack –When a port ACL is attached to the Catalyst 3750-E member switch port, add a Catalyst 3750 switch as a member if the stack does not have router ACLs configured with the ahp keyword, the routing keyword, or both. –When the router ACL is attached to an SVI on a member, add a Catalyst 3750-E switch as a member but not a Catalyst 3750 switch as a member.	The switch does not support the ahp and routing keywords in the deny (IPv6 access-list configuration) and the permit (IPv6 access-list configuration) command. If an ACL has ACEs with the ahp keyword, the routing keyword, or both, these actions occur on a standalone switch or on Catalyst 3750-only stack: •When you apply a port ACL to a switch port or a router ACL to an SVI, the switch rejects the ACL. •When you modify the port or router ACL by adding the ahp keyword, the routing keyword, or both to the ACE, the switch rejects the ACE.	If a port or router ACL has ACEs with the ahp keyword, the routing keyword, or both, these actions occur: •The port ACL can be applied only to a Catalyst 3750-E member switch port. •The port ACL cannot be applied to any Catalyst 3750 member switch port. •A router ACL cannot be applied to an SVI on any member switch. If a router ACL is applied to an SVI and you modify the ACL by adding the ahp keyword, the routing keyword, or both to the ACE, the switch rejects the ACE. If a port ACL is applied to a Catalyst 3750 member switch port and you modify the ACL by adding the ahp keyword, the routing keyword, or both to the ACE, the switch rejects the ACE. If a port ACL is applied to a Catalyst 3750-E member switch port and you modify the ACL by adding the ahp keyword, the routing keyword, or both to the ACE, the switch accepts the ACE.
	The switch supports IPv6 address-matching for a full range of prefix lengths.	—	—
IPv6 unicast routing	The switch has no limitations for ICMPv68 redirect.	The switch supports ICMPv6 redirect for routes with mask lengths less than 64 bits. ICMP redirect is not supported for host routes or for summarized routes with mask lengths greater than 64 bits.	When configuring equal-cost routes, the router might choose different paths, depending on the ingress switch.
MLD snooping	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. If a Catalyst 3750-E member receives an unmatched multicast packet, the switch forwards the packet in hardware.
MVR9	When the switch forwards a packet from a source VLAN to a receiver port, the switch does not modify the packet.	When the switch forwards a packet from an source VLAN to a receiver port, the switch modifies the source MAC address and decrements the TTL10 of the packet.	—
SDM templates	—	—	All stack members must use the same SDM template as the stack master.
show platform commands	The switch supports the show platform sf-asic privileged EXEC command to enable debugging of the ASIC data structures. The switch supports the show platform dl [detail] privileged EXEC command to display dynamically loaded module information.	—	—
STP11	—	—	All stack members must run the same version of STP.
Switch-based authentication	—	—	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. Because of collisions, in some cases, the switch cannot store a few MAC address table entries even if it has free hardware memory.	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.	—
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 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.
