Hi
I am doing a lab exercise in preparation for the BCMSN.
There is a 2950 access switch connected to two 3550 distribution switches.
On the 2950, fa0/1 and fa0/2 are connected to 3550A and fa0/3 and fa0/4 are connected to 3550B.
At the moment, ports fa0/1 - 4 on the 2950 are in VLAN99.
The instructions are to -
i) Assign fa0/1 - 4 back to VLAN1. ii) Turn on trunking on the ports connecting the 2950 and 3550's and use 802.1Q trunking.
My response was;
i)
2950#conf t 2950(config)# interface range fa0/1 - 4 2950(config-if-range)# switchport access vlan 1 2950(config-if-range)# switchport mode trunk 2950(config-if-range)# switchport trunk encap dot1qand then
3550A#conf t 3550A(config)# interface range fa0/1 - 2 3550A(config-if-range)# switchport mode trunk 3550A(config-if-range)# switchport trunk encap dot1qand also
3550B#conf t 3550B(config)# interface range fa0/1 - 2 3550B(config-if-range)# switchport mode trunk 3550B(config-if-range)# switchport trunk encap dot1qThe lab, however, states that it should be;
2950#conf t 2950(config)# interface range fa0/1 - 4 2950(config-if-range)# switchport access vlan 1 2950(config-if-range)# switchport mode trunk 2950(config-if-range)# switchport nonegotiateand then on both switches;
3550#conf t 3550(config)# interface range fa0/1 - 2 3550(config-if-range)# switchport mode trunk 3550(config-if-range)# switchport nonegotiate 3550(config-if-range)# switchport trunk encap dot1qWhich is correct, or is this just two ways of doing the same thing?
Thx
