mac-address: Local reachable MAC address of the router, in the form of H-H-H.

mask: MAC address mask in the form of H-H-H, functionally similar to a subnet 
mask.

mac-exclusivity: Allows the router to access only those designated MAC 
addresses.

saps-list: List of local reachable SAP addresses of the router, in the form of 
saps-list=saps-value&<1-120>, where saps-value must be an even number in the 
range of 0x10 to 0xFE and &<1-120> means that you can specify up to 120 SAP 
addresses or SAP address ranges with this argument.

Use the dlsw reachable command to configure a local reachable MAC address 
or SAP addresses of the router.

Use the undo dlsw enable command to remove the reachability configuration.

After the dlsw reachable command is issued, the router notifies all connected 
routers of the local reachable MAC address or SAP addresses. Based on this 
information, the remote routers can decide whether to send frames to, without 
first polling, this router.

Note that you must change the configuration in time when changes occur to the 
local network.
