Hi there...
One on our our 7606's we have a GigE link that is getting fairly "hot" with
traffic....
GigabitEthernet4/1 is up, line protocol is up (connected)
..
Input queue: 0/2000/438/0 (size/max/drops/flushes); Total output drops:
98911
5 minute output rate 817892000 bits/sec, 133528 packets/sec
...
406989787118 packets output, 241435931635384 bytes, 0 underruns
I've ordered a new x-connect with the idea of running etherchannel... my
real question is how much further can I push this link? There's no latency
or issues that are evident yet but wanted to ask anyways....
you're pushing it pretty hard already. a 5 minute average of 817 Mbps would
probably imply instantaneously pushing 1 Gbps.
more granular statistics (e.g. setting load-interval to 30 seconds) may show
more dynamic nature than a 5 minute average, but i'd say getting 15 or 30
second SNMP counters may show you hitting 1Gbps for periods of time.
latency would be a function of queuing & average queue length.
based on your statistics, you have 98K output queue drops (queue was full)
based on 406 billion packets -- so it clearly isn't happening _too_ often ...
yet .. :)
Why not add something like:
hold-queue 1024 out
hold-queue 1024 in
