VLAN trunking protocol on C2960-S switches

Discussion in 'Cisco' started by Michael T. Davis, Feb 10, 2012.

  1. I just received a C2960S-24TS-L, and discovered that it doesn't
    understand the "switchport trunk encapsulation dot1q" interface command. I
    did a Web search, and found a response about the fact that this was
    unrecognized because this model of switch only supports dot1q encapsulation,
    so the command was unnecessary. Is this accurate? I want to make sure the
    "vlan trunking protocol" is configured correctly before I put the switch into

  2. Yes that is correct. Only the legacy hardware (ie. 4500/6500) supports
    ISL trunking any longer, and the standard, dot1q, is the only way for
    new school switch hardware.

  3. It's true - I've done the same before and it's working fine with a dot1q
