Description

IPv6 address

IPv6 address in the ND snooping entry.

MAC address

MAC address in the ND snooping entry.

VID

ID of the VLAN to which the ND snooping entry belongs.

First VLAN ID

ID of the SVLAN to which the ND snooping entry belongs.

Second VLAN ID

ID of the CVLAN to which the ND snooping entry belongs. If no CVLAN is configured, this field displays N/A. For more information about the SVLAN and CVLAN, see Layer 2—LAN Switching Configuration Guide.

Interface

Input interface in the ND snooping entry.

Status

Status of the ND snooping entry:

  • TENTATIVE—The entry is ineffective.

  • VALID—The entry is effective.

  • TESTING TPLT—The entry is being tested by DAD. The device performs DAD for the entry in the following situations:

    • The entry ages out

    • An ND trusted interface in the VLAN receives an ND message from the IPv6 address in the entry.

  • TESTING VP—The entry is being tested by DAD. The device performs DAD when an ND untrusted interface in the VLAN receives an ND message from the IPv6 address in the entry.

Age

For an ND snooping entry in VALID status, this field displays its remaining aging time in seconds. For an ND snooping entry in other status, this field displays a pound sign (#).
