[f-nsp] CAM IP partition warning - Error Help MLXe X 1 million routes

[David Hubbard]

Would a cam profile change affect layer 3 services in a VRF?  :-)  

I just switched a test router to ipv4-ipv6-2 from default and lost my
management access via network.  I have a management vrf defined with a
gig port member since the management port can't be in a management vrf
in the code version I'm running.  After the reload, the router still
responds to arp requests but won't talk ssh, snmp or ntp, which are the
only services I have enabled, or respond to ping.  All the normal stuff
not in the vrf came up fine (bgp & ospf).

David,

I think ipv4-ipv6 is there really to preserve prior deployments that may
justify any adjustments to the cam-profile. I haven't found anyone who
uses that for any new deployments, unless its just for testing or just
very basic layer3. 

In most cases ipv4-ipv6-2 or multi-service-4 (or whatever its called)
seem the most attractive in comparison. This is all in reference to
XMR/MLXe. MLX itself (with or with out -X cards), is a different story.

Also, I think the cards state that they support 1million routes, but I
don't think there is a cam profile for exactly 1million routes for
IPv4..the rest of the capabilities get spread across ipv4/mpls/mac
address/acl's, etc. 

SSH at router#show mod | inc S2
S2: BR-MLX-10Gx4-X 4-port 10GbE Module
CARD_STATE_UP    
SSH at router#show cam-partition usage slot 2

CAM partitioning profile: ipv4-ipv6-2

Slot 2 XPP20SP 0:
            [IP] 786432(size),  282381(free), 064.09%(used)

	Trying to understand when you'd want to use ipv4-ipv6 vs
ipv4-ipv6-2
	
	Thanks,

	James,
	
	Did you also change the cam-partiion profile you are using?
	
	router#sh cam-part | i profile
	CAM partitioning profile: ipv4-ipv6-2
	
	If you're using the default profile, it will still have the tcam
carved
	for 512k IPv4 routes.
	
	Also, updating the cam profile takes a reload.
	
	Regards,
	Mike
