10.2.2 LM IDU Configuration
VLANs must be enabled on the Ethernet switch of both LM units in order for aggregated traffic to
traverse the wireless link properly. Link Aggregation can be enabled and disabled on the LM IDU by
means of a pulldown on the Ethernet tab in the web GUI, as shown in Figure 10-4.

Note: VLAN double-tagging is not supported when link aggregation is enabled. The Cisco
SLM2008 switch strips off VLAN tags ingressing into the LM Ethernet port.
