Got a 2821 router and two 3750 switches (stacked). I have the ip 192.168.200.2 on the vlan 1 int of the stacked switches (i know i should use a different vlan). the only way I can ping the router is to have one of the gig interfaces and then put a sub int of that gig interface with the ip address. I wanted to use both of the gig interfaces to go to the stacked 3750 to create an etherchannel. when i try to do the following, i cannot ping across:
description EtherChannel to 3750
no ip address
hold-queue 150 in
encapsulation dot1Q 1 native
ip address 192.168.200.1 255.255.255.0
no snmp trap link-status
I place the two gig interfaces in the port channel, but nada. is there another way i should be doing this?
I finally called TAC about this, low and behold I got an answer.
"Q. Are there differences between the on-board Gigabit Ethernet ports and the HWIC-1GE-SFP?
A. Two copper Gigabit Ethernet ports are built into the Cisco 2821, 2851, and 3800 Integrated Service Router platforms. On the Cisco 3800 Series platform, an SFP Gigabit Ethernet port can be used instead of one of the copper Gigabit Ethernet ports. The feature set of the on-board Gigabit Ethernet ports and the HWIC-1GE-SFP is the same, except that Cisco EtherChannel® is not supported on the on-board Gigabit Ethernet interfaces"
So...etherchannel is not supported on the gig interfaces on the 2821 if anyone would like this info.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
