DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
Command Default Level
Level: 12.
Usage Guideline
ND Snooping is designed for a stateless auto-configuration assigned IPv6 address and manually
configured IPv6 address. Before assigning an IPv6 address, the host must perform Duplicate Address
Detection first. ND snooping detects DAD messages (DAD NS and DAD NA) to build its binding
database. The NDP packet (NS and NA) is also used to detect whether a host is still reachable and
determine whether to delete a binding or not.
DHCPv6 Snooping sniffs the DHCPv6 packets sent between the DHCPv6 client and server in the
address assigning procedure. When a DHCPv6 client successfully got a valid IPv6 address, DHCPv6
snooping creates its binding database.
Example
This example shows how to enable DHCPv6 snooping.
Switch# configure terminal
Switch(config)# ipv6 snooping policy policy1
Switch(config-ipv6-snooping)# protocol dhcp
Switch(config-ipv6-snooping)#
38-3 limit address-count
This command is used to limit the maximum number of IPv6 snooping binding entries. Use the no
form of this command to revert to the default setting.
limit address-count MAXIMUM
no limit address-count
Parameters
MAXIMUM
Default
By default, there is no limit configured.
Command Mode
IPv6 Snooping Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is used to limit the number of IPv6 binding entries on which the IPv6 snooping policy is
applied. This command helps to limit the binding table size.
Example
This example shows how to limit the number of IPv6 snooping binding entries to 25.
Switch# configure terminal
Switch(config)# ipv6 snooping policy policy1
Switch(config-ipv6-snooping)# limit address-count 25
Switch(config-ipv6-snooping)#
Specifies the maximum number of IPv6 snooping binding entries.
The range is from 0 to 511.
