Optimizing Traffic Flow with Port Controls, Port Trunking, and Filters

Traffic/Security Filters

Protocol Filters

This filter type enables the switch to forward or drop, on the basis of protocol type, traffic to a specific set of destination ports on the switch. Filtered protocol types include:

AppleTalk

IP

SNA

ARP

IPX

 

DEC LAT

NetBEUI

 

Only one filter for a particular protocol type can be configured at any one time. For example, a separate protocol filter can be configured for each of the protocol types listed above, but only one of those can be an IP filter. Also, the destination ports for a protocol filter can be on different VLANs.

You can configure up to seven protocol filters.

 

Source-Port Filters

 

This filter type enables the switch to forward or drop traffic from all end nodes

 

on the indicated source-port to specific destination ports. If VLANs are

 

configured, the destination port must be in the same VLAN as the source-port.

 

Only one source-port filter can be configured for each of the ports in the

 

switch.

 

You can configure all destination ports in the switch on a single source-port

 

filter.

 

 

N o t e

If more than one VLAN is configured, then the set of destination ports (Dest

 

Port parameter) can consist of only the destination ports that are in the same

 

VLAN as the source-port.
