Port Parameters (applied to a specified port within a VLAN)
•Path Cost – a parameter used to assign a higher or lower path cost to a port. Possible values: 1 – 65535. Default is (1000/Port Speed) for

Configuring IP
NOTE: See “Configuring AppleTalk Cable VLANs” on page
Example: Suppose you want to create four separate Layer 3 broadcast domains within a single Layer 2 STP broadcast domain:
•Two broadcast domains, one for each of two separate IP
•One for IPX Network 1
•One for the Appletalk protocol
Also suppose you want a single router interface to be present within all of these separate broadcast domains, without using IEEE 802.1p VLAN tagging or any proprietary form of VLAN tagging.
