Understanding the SDM Templates

Table 8-2	Approximate Feature Resources Allowed by Dual IPv4-IPv6 Templates
		IPv4-and-IPv6	IPv4-and-IPv6	IPv4-and-IPv6
Resource		Default	Routing	VLAN
Unicast MAC addresses		2 K	1.5 K	8	K
IPv4 IGMP groups and multicast routes		1 K	1 K	1	K for IGMP
				groups
				0 for multicast

Total IPv4 unicast routes:		3 K	2.75 K	0
• Directly connected IPv4 hosts		2 K	1.5 K	0
• Indirect IPv4 routes		1 K	1.25 K	0
IPv6 multicast groups		1 K	1 K	1 K
Directly connected IPv6 addresses		2 K	1.5 K	0

SDM Templates and Switch Stacks

In a Catalyst 3750-E-only or a mixed hardware switch stack, all stack members must use the same SDM desktop template that is stored on the stack master. When a new switch is added to a stack, the SDM configuration that is stored on the stack master overrides the template configured on an individual switch. For more information about stacking, see Chapter 5, “Managing Switch Stacks.”

You can use the show switch privileged EXEC command to see if any stack members are in SDM mismatch mode. This example shows the output from the show switch privileged EXEC command when an SDM mismatch exists:

Switch#	show switch
				Current
Switch#	Role	Mac Address	Priority	State

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

*2	Master	000a.fdfd.0100	5	Ready
4	Member	0003.fd63.9c00	5	SDM Mismatch

This is an example of a syslog message notifying the stack master that a stack member is in SDM mismatch mode:

2d23h:%STACKMGR-6-SWITCH_ADDED_SDM:Switch 2 has been ADDED to the stack (SDM_MISMATCH)

2d23h:%SDM-6-MISMATCH_ADVISE: 2d23h:%SDM-6-MISMATCH_ADVISE:

2d23h:%SDM-6-MISMATCH_ADVISE:System (#2) is incompatible with the SDM 2d23h:%SDM-6-MISMATCH_ADVISE:template currently running on the stack and 2d23h:%SDM-6-MISMATCH_ADVISE:will not function unless the stack is 2d23h:%SDM-6-MISMATCH_ADVISE:downgraded. Issuing the following commands 2d23h:%SDM-6-MISMATCH_ADVISE:will downgrade the stack to use a smaller
