=1, Switch will pass 802.1x “flow control”
=0, Switch will drop 802.1x “flow control” packets
Reserved
Do not change the default value.
Reserved
Do not change the default value.
=1, Link change from “link” to “no link” will cause fast aging
(<800us) to age address table faster. After an age cycle is
complete, the age logic will return to normal aging (about 200 sec).
Note: If any port is unplugged, all addresses will be automatically
aged out.
