Limitations and Restrictions

You should review this section before you begin working with the switch. These are known limitations

that will not be fixed, and there is not always a workaround. Some features might not work as

documented, and some features could be affected by recent changes to the switch hardware or software.

This section contains these limitations:

• Cisco IOS Limitations, page 9

• Device Manager Limitations, page 15

Access Control List

These are the access control list (ACL) limitations:

• The Cisco Catalyst 3120 for HP Blade Switch has 964 TCAM entries available for ACLs in the

default and routing SDM templates instead of the 1024 entries that are available on the

Catalyst

3560 and Catalyst 3750 switches.

There is no workaround. (CSCse33114)

• When a MAC access list is used to block packets from a specific source MAC address, that MAC

address is entered in the switch MAC-address table.

The workaround is to block traffic from the specific MAC address by using the mac address-table

static mac-addr vlan vlan-id drop global configuration command. (CSCse73823)
