SNR S2940-8G-v2 Switch Configuration Guide
ULSM Configuration
causes Switch A on which ULPP is configured to process uplink switchover and avoid the data
dropped.
60.2 ULSM Configuration Task List
1. Create ULSM group globally
2. Configure ULSM group
3. Show and debug the relating information of ULSM
1. Create ULSM group globally
Command Explanation
Global mode
ulsm group <group-id>
no ulsm group <group-id> Configure and delete ULSM group globally.
2. Configure ULSM group
Command Explanation
Port mode
ulsm group <group-id> { uplink | downlink }
no ulsm group <group-id> { uplink | downlink } Configure the uplink/downlink port of ULSM
group, the no command deletes the up-
link/downlink port.
3. Show and debug the relating information of ULSM
Command Explanation
Admin mode
show ulsm group [group-id] Show the configuration information of
ULSM group.
debug ulsm event
no debug ulsm event Show the event information of ULSM, the
no operation disables the shown informa-
tion.
60.3 ULSM Typical Example
The above topology is the typical application environment which is used by ULSM and ULPP
protocol.
ULSM is used to process the port state synchronization, its independent running is useless, so
it usually associates with ULPP protocol to use. In the topology, SwitchA enables ULPP protocol,
it is used to switch the uplink. SwitchB and SwitchC enable ULSM protocol to monitor whether the
uplink is down. If it is down, then ULSM will execute the down operation for the downlink port to
shutdown it, so ULPP protocol of Swtich A executes the relative operation of the uplink switchover.
