Limitations and Restrictions
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.

Access Control List
• 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)
