Re: RSPAN

"RSPAN VLANs must be configured in VLAN configuration mode by using the *
remote-span* VLAN configuration mode command."

elease/12.2_55_se/configuration/guide/swspan.html#wp1200730

"However, when you enter the *encapsulation replicate *keywords when
configuring a destination port, these changes occur:

Packets are sent on the destination port with the same
encapsulationuntagged, Inter-Switch Link (ISL), or IEEE 802.1Qthat they
had on the source port.

Packets of all types, including BPDU and Layer 2 protocol packets, are
monitored.

Therefore, a local SPAN session with encapsulation replicate enabled can
have a mixture of untagged, ISL, and IEEE 802.1Q tagged packets appear on
the destination port"
