Switch 7700 Configuration Guide

Implementing STP on the Switch 7700 169
If the Max Age is too short, it results in frequent calculation of spanning tree or
misjudging the network congestion as a link fault. On the other hand, a Max Age
that is too long may make the bridge unable to find link failure in time and
weaken the network auto-sensing ability. The default setting is recommended.
By default, the bridge Max Age is 20 seconds.
Setting the Maximum Transmission Speed of the Specified Port
The maximum transmission speed of the Ethernet port is related to its physical
state and network structure. Users can configure it according to the actual
network situation.
Perform the following configurations in Ethernet port view.
If the max transmission speed on a port is too high, there will be too many packets
being transmitted per unit time, which occupies excessive network resources. the
default setting is recommended.
By default, the maximum transmission speed is 3 (a counter value without unit) on
all the Ethernet ports of the bridge.
Setting a Port to be an EdgePort
An EdgePort is not connected to any switch directly or indirectly through the
connected network.
Perform the following configurations in Ethernet port view.
In the process of recalculating the spanning tree, the EdgePort can transfer to the
forwarding state directly and reduce unnecessary transition time. If the current
Ethernet port is not connected with any Ethernet port of other bridges, this port
should be set as an EdgePort. If a specified port connected to a port of any other
