You can use counters in jnx-cos MIB ( 1.3.6.1.4.1.2636.3.15 ). They will give you per-queue drop counters for each interface. I use jnxCosIfqTailDropPkts for monitoring interfaces on EX switches. These are the counters you see in "show interface extensive" - dropped packets for for each queue. nic

[j-nsp] Interface tail drops vs. ifOutDiscards

2013-01-25 Thread Antti Ristimäki
