[c-nsp] mac-address-table flags on 7600/6500

[Dmitry Kiselev]

Hello!

Could anybody explain me flags shown on "show mac-address-table detail"
SP output. I see traffic lose for host with MAC address marked "Trp=Yes".
I already found quick fix "clear mac-address-table dynamic", but
situation repeating time to time, which starts to bother me...
Looking for root cause and finally - the solution. :)

P.S. C7600/RSP720-3CXL under 12.2(33)SRC4. Mod.3,4,7 - 6708-3CXL
