Use the following procedure to detect whether NPM8200 internal switches are overloaded.
- First check cables, SFPs, ports, and switch
- Check if NPM drops traffic (see solution #806)
- Check if firewall drops packets (fw ctl zdebug drop)
- Check if interface errors continue growing:
CBS# clear interface gigiabitethernet 1/1
CBS# show interface gigabitethernet 1/1
Gigabitethernet 1/1 is up
Hardware address is 00:03:d2:11:b2:26
MTU 1500 bytes, BW 1 Gigabit, full-duplex, auto-negotiation is enabled
Last clearing of "show interface" counters never
