The following table describes commonly used parameter notation for these commands.
The following section lists the commands for this feature.
13.3 Daisy Chain Commands
Use the
daisychain
commands to set the IES to use one Gigabit Ethernet NNI as a downlink to
connect to another daisy chained IES. The other Gigabit Ethernet uplink port connects to the
Ethernet backbone. This is also called subtending. The daisy chain switch mode is recommended for
use in a network topology that does not have loops. When you daisy chain multiple IESs, all except
the last one in the change must have daisy chain enabled.
You can enable daisy chain on one Gigabit Ethernet uplink port at a time. When you enable daisy
chain, the daisy chain-enabled port serves as the subtending port (connect it to the downlink
device). The IES treats a daisy chain-enabled Gigabit Ethernet uplink port as a downlink and follows
the port isolation setting. Daisy chain mode with port isolation enabled blocks direct
communications between subscriber ports on an individual IES and the subscriber ports of the daisy
chained IESs.
The following section lists the commands for this feature.
13.4 Forwarding Database Commands
Use these commands to configure the forwarding database settings and display the forwarding
database address table. You can set the aging time, flush the address table, show the learned
entries count, display the address table, display the entries for specific ports, UNI VLANs, untagged
UNI VLANs, set the maximum number of MAC entries for specific ports, configure a static unicast
