从打封装端口接收的数据都是携带802.3qVLAN信息的
从打封装端口接收的数据可以不携带802.3qVLAN信息
第23题:
A Catalyst switch cannot have ISL and IEEE 802.1q trunks enabled.
All Catalyst switches support ISL trunking.
A Catalyst switch will report giants if one side is configured for ISL while the other side is not.
ISL trunking requires that native VLANs match.
None of the other alternatives apply
