Algorithm
This parameter sets the bridge's spanning tree algorithm to operate in normal (RSTP) or force it to
operate in slow (STP) mode. In normal mode, RSTP reverts back to STP on ports where it sees
other hosts operating in STP mode.
Ports settings
Port name
Identification of the internal switch port. The switch ports are connected to an external port or to an
internal device (radio modem, management CPU).
• Eth1 (port1) — The external port (with RJ45 interface) labeled "ETH1+POE".
• Eth2 (port10) — The external port (with SFP interface) labeled "ETH2".
• CPU (port0) — The internal port to management CPU.
• Air (port9) — The internal port to radio modem, i.e. link to the peer unit.
Port priority
The ports' priority value is a number between 0 and 240 in increments of 16, with a default value
of 128.
Path cost
The Path cost indicates "suitability of the link for the data transmission" and it is used in networks
with redundant connections to choose the best route for packets.
The Path cost can be set automatically or manually.
Entering the value of zero sets this para-
meter automatically.
The automatic setup is based on link speed. It is calculated as 20 Tbits/sec
divided by a link capacity.
For manual settings, lower value increase probability the link is chosen as a primary one for the
data transmission.
Edge
Selecting the checkbox sets the port as an "edge" port. If a port is an edge port it is assumed to be
a leaf link in the graph, not connected to any other bridges. Receiving any STP BPDU's on a port
configured as an edge port temporarily overrides edge port behavior for the port.
MAC address
The ports' default MAC addresses are the same as the MAC address of the unit. Value can be
overwritten by a user.
