10.3.4 (Optional) Configuring the Aging Function of the ND
Dynamic Binding Table
Through the aging function, the S2700 can automatically manage the ND dynamic binding table.
Context
After ND snooping is enabled, the S2700 establishes the ND dynamic binding table based on
the user information.
When the lease of ND dynamic binding entries expires, if the aging function of the ND dynamic
binding table is configured, the S2700 sends NS messages according to the number of detection
times and the detection interval for aging ND dynamic binding entries. If the user does not send
NA messages after the specified number of detection times, the S2700 considers that the user is
not online. Then the S2700 deletes the ND dynamic binding entry of the user and does not
forward messages to the user.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
nd user-bind detect enable
The aging function of the ND dynamic binding table is enabled.
Issue 01 (2011-07-15)
The interface view is displayed.
3. Run:
nd snooping trusted
The interface is configured as the trusted interface.
Configuring ND snooping in a VLAN
1. Run:
system-view
The system view is displayed.
2. Run:
vlan vlan-id
The VLAN view is displayed.
3. Run:
nd snooping trusted interface interface-type interface-number
The interface in the VLAN is configured as the trusted interface.
NOTE
When you run the nd snooping trusted command in the VLAN view, the specified interface
must belong to the VLAN. Compared with the nd snooping trusted command run in the
interface view, the nd snooping trusted command run in the VLAN view is more accurate
because a specified interface in a specified VLAN can be configured as a trusted interface.
