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 dot1q
and 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 dot1q
and 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 dot1q
The 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 nonegotiate
and 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 dot1q
Which is correct, or is this just two ways of doing the same thing?
Thx
