uni-mng

Usage Scenario

When SVF is disabled, the uni-mng command enables SVF and displays the uni-mng view. When SVF has been enabled, this command displays the uni-mng view.

Prerequisites

• A source interface used to set up a CAPWAP link has been specified using the capwap source interface vlanif vlan-id command.

• The STP working mode must be STP or RSTP. If the current working mode is not STP or RSTP, run the stp mode { rstp | stp } command to set the STP working mode to STP or RSTP before enabling SVF. By default, the STP working mode is MSTP. You can run the display stp command to check the current STP working mode.

• The default STP/RSTP port path cost algorithm must be used. If the current port path cost algorithm is not the default one, run the undo stp pathcost-standard command to restore the default port path cost algorithm before enabling SVF. The default STP/RSTP port path cost algorithm is IEEE 802.1t (dot1t). You can run the display stp command to check the current port path cost algorithm.

• The default Eth-Trunk specifications are used. If the current Eth-Trunk specifications are not the default value on S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6730-H, S6730S-H, S6730-S, S6730S-S, S6720-EI, or S6720S-EI, run the undo assign trunk command to restore the default Eth-Trunk specifications before enabling SVF. You can run the display trunk configuration command to check the default and configured Eth-Trunk specifications.

• The NAC configuration mode must be the unified mode. If the current mode is not the unified mode, run the authentication unified-mode command to set the NAC configuration mode to unified mode. The default NAC configuration mode is unified mode. You can run the display authentication mode command to check the current NAC configuration mode.

• Remote authorization is not configured in the system. If remote authorization has been configured, run the undo remote-authorize command to disable remote authorization before enabling SVF. By default, remote authorization is not configured in the system. You can run the display current-configuration command to check whether remote authorization is configured.

Precautions

• When SVF is enabled on the parent, LLDP is automatically enabled on the parent if LLDP is disabled. When SVF is disabled on the parent, LLDP is not automatically disabled on the parent.

• When SVF is disabled on the parent, the STP priorities of ports change, and STP recalculates the port role and changes the interface status.

• After SVF is enabled on a switch used as the parent, the stack timer mac-address switch-delay value changes to 0 (not changing system MAC address) and cannot be changed. After SVF is disabled on this switch, this delay time is still 0, but you can manually change it.
