Parameter 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-valuemust 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.

Description 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.

Example # Permit access to MAC addresses that start with 1212.

<Sysname> system-view

[Sysname] dlsw reachable mac-address 1212-1212-1212 mask ffff-0000-0000

# Allow the router to access SAP addresses 12 and 14.
