Troubleshooting access lists

Check if an ACL is active or not:

l

Run the command show access-lists and identify the desired ACL.

l

Identify the value of the Status field.

l

If the value of the Status field is Inactive then:

l

Identify the value of the In Port List and Out Port List fields. If both are NIL, the ACL is

inactive, as it has not been applied on any port.

l

Run the command show access-lists resources.

l

Check if the number of hardware policies reached the maximum. Once the number of

hardware policies in use reaches the maximum, new rules will be marked as inactive.

Static MAC

Managing Static MAC

The switch allows the user to configure a static MAC address and assign it to a specific VLANID and a

specific port. The MAC addresses configured in this manner are immune to automatic MAC address aging

and migration.

Normally, with a dynamically learned MAC address, traffic that enters the switch through a different port

than the one currently present in the mac-address-table will be forwarded, and the entry’s port will be

migrated to the new value.

Traffic that enters the switch through a port and has a source MAC address that is statically configured to

a different port will be dropped, and its source address will not be migrated.

Standards

l

IEEE 802.1q.

Scaling Numbers

l

256 static MAC addresses can be configured on the switch.

Limitations

l

Only unicast MAC addresses can be configured using this switch.

l

A valid entry in the mac-address-table is a MAC or VLAN id pair, and assigning the same pair to

more than one port will cause the switch to retain only the value configured last.

Default Values

l

The status of the static unicast entry is set to permanent by default.

Prerequisites

l

The VLAN to which the MAC address is assigned must be already created at the time the static

MAC is configured, or an error message will be displayed.
