the binding table.
Parameters
These parameters are displayed:
◆
MAC Address – Physical address associated with the entry.
◆
IP Address – IP address corresponding to the client.
◆
Lease Time – The time for which this IP address is leased to the client.
◆
Type – Entry types include:
■
DHCP-Snooping – Dynamically snooped.
■
Static-DHCPSNP – Statically configured.
◆
VLAN – VLAN to which this entry is bound.
◆
Interface – Port or trunk to which this entry is bound.
◆
Store – Writes all dynamically learned snooping entries to flash memory. This
function can be used to store the currently learned dynamic DHCP snooping
entries to flash memory. These entries will be restored to the snooping table
when the switch is reset. However, note that the lease time shown for a
dynamic entry that has been restored from flash memory will no longer be
valid.
◆ Clear – Removes all dynamically learned snooping entries from flash memory.
