Cisco Bug: CSCta03608 - counter mismatch between Rx and Tx side for the FR subif
Jan 07, 2017
- Cisco 12000 Series Routers
Known Affected Releases
3.8.2.BASE 3.9.0.BASE 4.0.0.BASE
Symptoms: o/p of <CmdBold>show inteface <CmdArg>main interface<noCmdArg><noCmdBold> and <CmdBold>show interface <CmdArg>sub interface<noCmdArg><noCmdBold> may not match. Total sub interface counts(for all sub interfaces under the main interface) may be larger on the egress side or smaller on the ingress side. FR subinterface counters are taken from the engine, while main interface counters are taken from the spa. This can result in a mismatch of counters at sub interface and main interface levels. Conditions: This mismatch is seen between FR sub interfaces and main interface counts. Mismatch occurs when packet rate becomes more than what the queuing asic can handle. This results in a queuing asic drop and a difference in main interface and sub interface counts.
