Command Syntax and Usage | |
---|---|
prior <new port Priority (0-255)> | |
Configures the port priority. The port priority helps determine which bridge port becomes the designated port. In a network topology that has multiple bridge ports connected to a single segment, the port with the lowest port priority becomes the designated port for the segment. Values: 0 – 255 Default: 128 | |
cost <new port Path Cost (0-65535, 0 for default)> | |
The contribution of this port to the path cost of paths towards the spanning tree root that includes this port. The port path cost assigns lower values to high-bandwidth ports, such as Gigabit Ethernet, to encourage their use. The cost of a port also depends on whether the port operates at full-duplex (lower cost) or half-duplex (higher cost). For example, if a 100 Mbps (Fast Ethernet) link has a “cost” of 10 in half-duplex mode, it will have a cost of 5 in full-duplex mode. The objective is to use the fastest links so that the route with the lowest cost is chosen. A value of 0 indicates that the default cost will be computed for an auto-negotiated link speed. Note: All ports in a trunk must have the same cost value. Values: 0 – 65535 Default: 20000 | |
link auto|p2p|shared | |
Sets the port link type. Values: ![]() ![]() ![]() Default: auto | |
edge disable|enable | |
Enables or disables the edge port. A port that does not connect to a bridge is called an edge port. Edge ports are generally connected to a server. Edge ports can start forwarding as soon as the link is up. Edge ports do not take part in a spanning tree configuration, and should not receive BPDUs. If a port with edge enabled does receive a BPDU, it begins STP processing only if it is connected to a spanning tree bridge. If it is connected to a host, the edge port ignores BPDUs. Default: disable | |
blkbpdu disable|enable | |
Enables or disables blocking the forwarding of configuration bridge protocol data units (BPDU), when the spanning tree is turned off. Applicable in ADC-VX mode. In a hot-standby configuration in global administrator or vADC environments, Radware recommends that you enable this option only on the ISL port. Otherwise, your network may create a Layer 2 loop and the upstream switch blocks its port, where all ports are still forwarding Layer 2 information via the ADC-VX. Default: disable | |
on | |
Enables STP on the port. STP is turned on by default for the port. | |
off | |
Disables STP on the port. | |
cur | |
Displays the current STP port parameters. |
