Netman, I have this product as well, what was the time at which he mentioned this trap?
was he talking about just a normal link up / link down trap? i am going to listen to it again and see if i can hear when he says, because i looked in the 3560 config guide and do not see anything other than this reference to traps in the etherchannel section and i didnt see it in the 'traps' section for PAGP or LACP: "If a link within an EtherChannel fails, traffic previously carried over that failed link moves to the remaining links within the EtherChannel. If traps are enabled on the switch, a trap is sent for a failure that identifies the switch, the EtherChannel, and the failed link. Inbound broadcast and multicast packets on one link in an EtherChannel are blocked from returning on any other link of the EtherChannel. " and you can see this in the "debug snmp packets" 00:16:11: %LINK-3-UPDOWN: Interface Port-channel1, changed state to down 00:16:11: SNMP: Queuing packet to 1.1.1.2 00:16:11: SNMP: V1 Trap, ent ciscoSyslogMIB.2, addr 1.1.1.1, gentrap 6, spectrap 1 clogHistoryEntry.2.22 = LINK clogHistoryEntry.3.22 = 4 clogHistoryEntry.4.22 = UPDOWN clogHistoryEntry.5.22 = Interface Port-channel1, changed state to down clogHistoryEntry.6.22 = 97125 00:16:11: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down 00:16:11: SNMP: Queuing packet to 1.1.1.2 00:16:11: SNMP: V1 Trap, ent ciscoSyslogMIB.2, addr 1.1.1.1, gentrap 6, spectrap 1 clogHistoryEntry.2.23 = LINK clogHistoryEntry.3.23 = 4 clogHistoryEntry.4.23 = UPDOWN clogHistoryEntry.5.23 = Interface GigabitEthernet1/0/1, changed state to down clogHistoryEntry.6.23 = 97127 Switch#sh etherchannel summary Number of channel-groups in use: 1 Number of aggregators: 1 Group Port-channel Protocol Ports ------+-------------+-----------+----------------------------------------------- 1 Po1(SD) - Gi1/0/1(D) -- Garry L.
