[c-nsp] Adjusting TCAM allocation weird behavior on 7600

[Mack McBride]

Your maximum must add up correctly.
The current settings do not equal 1024.
Multicast and IPv6 count for two each.

The easiest way to ensure this is working properly is to not set ip and mpls.

Our configuration is:

mls cef maximum-routes ipv6 192
mls cef maximum-routes ip-multicast 1

For what you want, you would do:

mls cef maximum-routes ipv6 100
mls cef maximum-routes ip-multicast 28
no mls cef maximum-routes ip 750
no mls cef maximum-routes mpls 10

The MPLS and ip will be shared and equal.

Subject: [c-nsp] Adjusting TCAM allocation weird behavior on 7600

Hi, I'd like to ask anyone in the group who owns cisco 7600 if they had experience when they adjusted the allocation to increase the maximum routes for ipv4 etc. We are near the 512K ipv4 limit (~509K) for the
7600 (default size) and I tried adjusting the tcam allocation by running:

mls cef maximum-routes ip 750
mls cef maximum-routes ipv6 100
mls cef maximum-routes mpls 10
mls cef maximum-routes ip-multicast 28

But after rebooting the whole box I got an error, "Maximum routes config mismatch. reconfigure the maximum routes values and reload the box" (Sorry this is all I copied from the console) and the tcam was back to the default values.

I have a dual RSP720-3CXL-10GE sups on sso mode and c7600rsp72043-adventerprisek9-mz.153-1.S1.bin if those info help.

Thanks,
