3550 sdm template

Hi,

I'm using 3550 12.1(12c)EA1 as access routeur. When I add an Input ACL I have an FM-3-Unloaded message.

I'm using the SDM access template.

How can I select which ACL will be installed in Tcam ?

How can I see which tcam is used 1 or 2 ?

Re: 3550 sdm template

see these two examples where small ACL can cause Tcam merge failure :

case-1 "sdm template: Access"

Switch1(config)#access-list 109 permit ip 205.167.139.0 0.0.0.255 any

Switch1(config)#access-list 109 permit tcp any 63.175.108.0 0.0.0.255

Switch1(config-if)#ip access-group 109 out

Switch1(config-if)#

09:13:04: %FM-3-UNLOADING: Unloading output label 1 feature

Switch1(config-if)#

case-2 "sdm template: Default"

Switch2(config)#access-list 182 deny ip any 192.168.0.0 0.0.255.255

Switch2(config)#access-list 182 permit ip 142.34.100.0 0.0.1.255 any

Switch2(config)#access-list 182 permit ip 142.34.92.48 0.0.0.7 any

Switch2(config)#int G0/1

Switch2(config-if)#ip access-group 182 in

Switch2(config-if)#

01:11:13: %FM-3-UNLOADING: Unloading input label 1 feature >!]

This is infact a limitation of 3550; If you upgrade to at least 12.1(9)EA1c , this problem can be solved.

Check the link for more details:

Hope this helps.
