THE SHORT QUESTION:
How can I see how full my IPv4 FIB is, on an EX8200 with EX8200-40XS
linecards and 11.3R2.4 ? I can connect to fpc and give the show
commands, but I need help interpreting the results.
If it actually turns out to be full, is there something I should do to
support the 500K routes that I see in the data sheet? I mean e.g.
something like the sdm templates or "mls cef maximum-routes" in the
cisco boxes?
THE LONG, PAINFUL STORY:
I have a pair of such machines, configured to take IPv4 and IPv6 full
routing table in a routing instance.
The datasheets say that I should be able to take 500.000 IPv4 and
250.000 IPv6 routes, and now I have 370K and 7K active routes:
internet.inet.0: 370806 destinations, 741349 routes (370798 active, 0
holddown, 8 hidden)
internet.inet6.0: 7161 destinations, 7168 routes (7161 active, 0
holddown, 0 hidden)
I am experiencing issues where traffic to some destinations is lost
while other destinations work, so I would like to see if the TCAM
utilization is OK. The issue was present also with some 10.x releases I
tried before, so it is not specific to this release.
I tried to open a session to the fpc with "vty fpc2", and it prints log
lines like this:
[Wed Oct 12 15:39:48 2011 LOG: Err] Failed to Add IPv4 Uc prefix/len

[Wed Oct 12 15:39:48 2011 LOG: Err] RT-HAL,rt_msg_handler,580: route
process failed
And so on for more IPv4 prefixes. Similar lines are also in messages.
This looks very much like a TCAM full error to me, but TCAM utilization
doesn't seem anywhere full. This is the (cleaned) transcript of my
attempt to see the TCAM utilization:

The other instances of vendor 6 are similar. Instances of vendor 7 give
no information, showing only zeroes. The number shown are not giving me
any clue.
Besides, if it actually is a TCAM full issue, why is it happening? The
box with these cards should support 500K IPv4 routes, am I doing
something wrong? Should I repartition the TCAM in some way, as I'm used
to do with cisco boxes? I find no mention of this kind of configuration
in the docs.
Thanks in advance for your kind replies.
