VLAN to WLAN-GW IOM/IMM Steering via Internal Epipe
The aggregation network can insert up to two AP identifying VLAN tags, and the AP can insert a .1q tag (typically for identifying the SSID). The number of AP identifying tags sent on the internal epipe depends on the encapsulation on the access SAP. For example, if an aggregation network inserts two AP identifying tags, and an access SAP is configured with null encaps, then the traffic sent on the internal Epipe will carry two AP identifying tags. The number of AP identifying tags in the frame forwarded over the internal Epipe must be configured via the l2-ap-encap-type command.
