CAM IP partition warning – Error Help MLXe X 1 million routes
Hi All

We are using both 5.3d and 5.4d on different devices and getting the same errors on different MLXe X platform, which should support 1 million routes.

CAM IP partition warning: total 524288 (reserved 0), free 26214, slot 3, ppcr 1

However we have increased the ip-route and ip-cache cam to maximum:

System Parameters Default Maximum Current Actual Bootup Revertible
mac 131072 2097152 131072 131072 131072 Yes
vlan 512 4095 1024 1024 1024 No
spanning-tree 32 128 32 32 32 No
rstp 32 128 32 32 32 No
ip-arp 8192 65536 8192 8192 8192 No
ip-cache 204800 1048576 1048576 1048576 1048576 Yes
ip-route 204800 1048576 1048576 1048576 1048576 Yes


Whilst the error is for 500k routes the maximum is set to 1 million routes, what could be causing these errors ?

Thanks

James

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

Re: CAM IP partition warning - Error Help MLXe X 1 million routes [ In reply to ]
Is there a table that shows the values that are used for -X cards with
the ipv4-ipv6 and ipv4-ipv6-2 profiles? Only one I could find seems to
be for the normal cards

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

Thanks,

David

Re: CAM IP partition warning - Error Help MLXe X 1 million routes [ In reply to ]
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@router#show mod | inc S2
S2: BR-MLX-10Gx4-X 4-port 10GbE Module CARD_STATE_UP

SSH@router#show cam-partition usage slot 2

CAM partitioning profile: ipv4-ipv6-2

Slot 2 XPP20SP 0:

Re: CAM IP partition warning - Error Help MLXe X 1 million routes [ In reply to ]
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).
