● Enter an aging time (in seconds) in CONFIGURATION mode, from 0 to 1000000, default 1800.
mac address-table aging-time seconds
NOTE: On the Dell EMC PowerSwitch S4200-ON series, the default MAC aging time is set as 550 seconds. This is the
maximum value that can be configured.
Configure Aging Time
OS10(config)# mac address-table aging-time 900
Disable Aging Time
OS10(config)# mac address-table aging-time 0
NOTE: When continuous MAC address movement occurs in a Virtual Link Trunking (VLT) environment, it results in MAC
pointing to VLT interconnect on both nodes and it causes traffic loss. This condition gets resolved automatically when the
MAC aging time lapses or when MAC is assigned to a single port after the continuous MAC movement stops. To solve this
issue manually, use the clear mac address-table command to remove the MAC address entry from the MAC address
table. This limitation is applicable to both VLAN and PVLAN.
Static MAC Address
You manually configure a static MAC address entry. A static entry is not subject to aging.
● Create a static MAC address entry in the MAC address table in CONFIGURATION mode.
mac-address-table static nn:nn:nn:nn:nn vlan vlan-id interface [ethernet node/slot/
port[:subport] | port-channel channel-number]
NOTE:
Before using the mac-address-table static command, create the required VLANs. If you do not create a
VLAN before configuring a static MAC address entry, the system displays an error message.
Set Static MAC Address
OS10(config)# interface vlan 10
OS10(conf-if-vl-11)# exit
OS10(config)# mac address-table static 34:17:eb:f2:ab:c6 vlan 10 interface ethernet 1/1/5
MAC Address Table
OS10 maintains a list of MAC address table entries.
● View the contents of the MAC address table in EXEC mode.
show mac address-table {dynamic | static} [address mac-address | vlan vlan-id |
interface {ethernet node/slot/port[:subport] | port-channel number}] [count [vlan
vlan-id] [interface {type node/slot/port[:subport] | port-channel number}]
