MLX cam partition issue

ser_gregor — Thu, 25 Apr 2019 19:38:55 GMT

Hello  I have a warning in log about cam partition free space. Now profile is ipv4-ipv6-2 and table is almost full
[ip] 786432(size), 39005(free), 095.04%(used)
[IPV6] 65536(size), 6250(free), 090.46%(used)

There are other profiles but i couldn't find any documentation about exact values. Could you please help me?

Hello,

The details of the profiles can be found in the management guide. If you do a search for cam-partition then it should get you to the appropriate section. There are quite a few tables that show the amount of resource that is available for each of the profiles.

The profile also depends which line cards you got installed. For a DFZ BGP table you need to upgrade to X2 cards for more IPv4/IPv6 route space, else you need to build up some prefix filters, because we are reaching the 768k limit soon.

Valid modules:

code:

- BR-MLX-100Gx2-CFP2-X2
	-> 2 x 100g
- BR-MLX-10GX20-X2 in its variants:
	-> BR-MLX-10Gx20-X2
		-> 20 x 1g/10g
	-> BR-MLX-10Gx10-X2
		-> 10 x 1g/10g, upgradeable to 20 10g/20g
	-> BR-MLX-1GX10-U10G-X2
		-> 20 x 1g, upgradeable to 20 10g/20g

Valid cam-profiles (limits apply only with modules from above, else other limits apply)

code:

- default (1424K mil ipv4, 416K ipv6)
- multiservice-6 ( 1120K ipv4, 768K ipv6)
- ipv4-ipv6-2 (2048K ipv4, 1024K ipv6, no VPN)

I built

to block some routes from regions, that I am not interested in, e.g. LACNIC.

Hi joergkost,
you are absolutely right, bgp table grows quick and for MLXs it is a problem
Thanks a lot for a tip 
