Table 197 MAC Address Forwarding Table Maximum Size CLI Parameters
Parameter Input Type
mac limit Number
The following command limits the number of dynamic MAC address forwarding table entries for Service 10 to 128:
service[10]>service mac-limit-value set 128
Setting the MAC Address Forwarding Table Aging Time (CLI)
You can configure a global aging time for dynamic entries in the MAC address forwarding table. Once this aging
time expires for a specific table entry, the entry is erased from the table.
To set the global aging time for the MAC address forwarding table, enter the following command:
root> ethernet service learning-ageing-time set time <time>
Table 198 MAC Address Forwarding Table Aging Time CLI Parameters
Parameter Input Type
time Number
The following command sets the global aging time to 2500 seconds:
root> ethernet service learning-ageing-time set time 2500
To display the global aging time for the MAC address forwarding table, enter the following command:
root> ethernet service learning-ageing-time show
Adding a Static MAC Address to the Forwarding Table (CLI)
You can add static entries to the MAC forwarding table. The global aging timer does not apply to static entries, and
they are not counted with respect to the maximum size of the MAC address forwarding table. It is the
responsibility of the user not to use all the entries in the table if the user also wants to utilize dynamic MAC
address learning.
To add a static MAC address to the MAC address forwarding table, go to service view for the service to which you
want to add the MAC address and enter the following command:
service[SID]>service mac-learning-table set-static-
mac <static mac> spid <sp-id>
To delete a static MAC address from the MAC address forwarding table, go to service view for the service from
which you want to delete the MAC address and enter the following command:
Permitted Values
