SMC Networks TigerSwitch 100 manual Spanning Tree Protocol Configuration

SPANNING TREE PROTOCOL CONFIGURATION

begins learning addresses.

-Forwarding — Port forwards packets, and continues learning addresses.

•Priority — Defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch is the same, the port with the highest priority (i.e., lowest value) will be configured as an active link in the Spanning Tree. This makes a port with higher priority less likely to be blocked if the Spanning Tree Protocol is detecting network loops. Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled. (Default: 128; Range: 0-240, in steps of 16)

•Path Cost — This parameter is used by the STP to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. (Path cost takes precedence over port priority.)

-Range —

Ethernet: 200,000-20,000,000

Fast Ethernet: 20,000-2,000,000

Gigabit Ethernet: 2,000-200,000

-Defaults —

Ethernet — half duplex: 2,000,000; full duplex: 1,000,000; trunk: 500,000

Fast Ethernet — half duplex: 200,000; full duplex: 100,000; trunk: 50,000

Gigabit Ethernet — full duplex: 10,000; trunk: 5,000

Note: When the Path Cost Method is set to short, the maximum path cost is 65,535.

•Admin Link Type — The link type attached to this interface. (Default: Auto)

-Point-to-Point— A connection to exactly one other bridge.

-Shared — A connection to two or more bridges.
