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

[Vinny_Abello at Dell.com]

If you want to carry full IPv4 routes, you'll have to use ipv4-ipv6-2, or multi-service-4, however the IPv6 routes on multi-service-4 will probably not be enough for very long. If you're not carrying full routes, you can adjust based on your needs. Just follow the tables in the cam partitioning profiles to find a cam partition that matches your needs, then adjust your system-max values for ip-cache and ip-route accordingly once you have a cam profile that can support what you're trying to set.

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

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

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
