23.1.7 Clearing MAC address table

Port down #1

Learned entries are deleted from the corresponding port.

Channel Group Down #2

Learned entries are deleted from the corresponding channel group.

Execution of the clear mac-address-table operation command

The MAC address table is cleared according to the parameters.

Clear MIB set for the MAC address table

(private MIB)

The MAC address table is cleared at setup.

Spanning Tree topology changed

When Spanning Tree Protocols are configured on the Switch:

The MAC address table is cleared when a topology change is detected.

When the Switch runs as a ring node in a network configuration using a Spanning Tree Protocol and Ring Protocol:

The MAC address table is cleared when a flush control frame sent during a topology change for a switch using the Ring Protocol is received.

GSRP master/backup switched

When the Switch runs as a GSRP switch:

The MAC address table is cleared when the switch becomes the backup.

When the Switch runs GSRP-aware:

The MAC address table is cleared when the GSRP Flush request frame sent when the GSRP switch becomes the master is received.

When the Switch uses both GSRP and the Ring Protocol:

The MAC address table is cleared when the switch becomes the master.

When the Switch runs as a ring node in a network configuration using both GSRP and the Ring Protocol:

The MAC address table is cleared when the flush control frame sent when a switch using the Ring Protocol becomes the master is received.

Route switched by the Ring Protocol

When the Switch runs as the master node:

The MAC address table is cleared when path switching is performed.

When the Switch runs as a transit node:

The MAC address table is cleared when the flush control frame sent from the master node when path switching is performed is received.

The MAC address table is cleared when the maintenance time for waiting for the flush control frame times out.

When the multi-fault monitoring functionality is enabled, if receiving flush control frames sent from a shared node when switching to or switching back from a backup ring, the MAC address table is cleared.

The MAC address table is cleared when the neighboring-ring flush control frame sent from the master node when path switching is performed is received.

VRRP virtual router master/backup switched

The MAC address table is cleared when the Flush Request frame sent when the VRRP virtual router becomes the master is received.

Primary port and secondary port switched due to uplink/redundancy functionality

The MAC address table is cleared when the flush control frame sent on switching from the primary port to the secondary port or on switching back from the secondary port to the primary port is received.

Setting MAC address-learning suppression configuration (in VLAN)

If MAC address learning suppression is set by using the configuration command no mac-address-table learning, entries learned by the corresponding VLAN are deleted.

Port down #1

[VXLAN Access]

Learned entries are deleted from the corresponding port.

[VXLAN Network]

Entries learned from the applicable port are not deleted.

Channel Group Down #2

[VXLAN Access]

Learned entries are deleted from the corresponding channel group.

[VXLAN Network]

Entries learned from the corresponding channel group are not deleted.

Execution of the clear mac-address-table operation command

MAC address table learned by VNI is also cleared according to the parameters.

Execute operation-command clear vxlan mac-address-table

MAC address table learned by VNI is cleared according to the parameter.

Deletes the destination IP for VXLAN tunneling

Deletes entries learned on the target VNI.

Spanning Tree topology changed

When Spanning Tree Protocols are configured on the Switch:

The MAC address table is cleared when a topology change is detected.

GSRP master/backup switched

When the Switch runs as a GSRP switch:

The MAC address table is cleared when the switch becomes the backup.

When the Switch runs GSRP-aware:

The MAC address table is cleared when the GSRP Flush request frame sent when the GSRP switch becomes the master is received.

When the Switch uses both GSRP and the Ring Protocol:

The MAC address table is cleared when the switch becomes the master.

When the Switch runs as a ring node in a network configuration using both GSRP and the Ring Protocol:

The MAC address table is cleared when the flush control frame sent when a switch using the Ring Protocol becomes the master is received.

VRRP virtual router master/backup switched

The MAC address table is cleared when the Flush Request frame sent when the VRRP virtual router becomes the master is received.

Primary port and secondary port switched due to uplink/redundancy functionality

When a flush control frame is received, MAC address table is cleared.

Setting MAC address-learning suppression configuration (in VNI)

If MAC address learning suppression is set by using the configuration command no mac-address-table learning, entries learned by the corresponding VNI are deleted.
