8-10 Rapier Switch Software Reference
Software Release 2.7.3
C613-03098-00 REV A
■ terminate on the same device
■ be members of the same VLANs
■ have the same data rate
■ share the same admin port key (assigned by using the command, add lacp
port command on page 8-71).
The hardware must also be capable and have the capacity to handle the
number of links to be aggregated.
Aggregated group identification
In order to identify particular aggregated groups, each group is assigned a link
aggregation identifier called a lag ID. The lag ID comprises the following
components for both the local system (called the Actor) followed by their
equivalent components for the remote system (called the Partner):
■ system priority - set by the set lacp priority command on page 8-147.
■ system identifier - the MAC address of the system
■ port key - An identifier - created by the LACP software
■ port priority - set by the command, add lacp port command on page 8-71.
■ port number - determined by the device connection
The lag ID can be displayed for each aggregated link by entering the command,
show lacp trunk command on page 8-186
Packet Storm Protection
The packet storm protection feature allows the user to set limits on the
reception rate of broadcast, multicast and destination lookup failure packets.
The software allows separate limits to be set for each port, beyond which each
of the different packet types are discarded. The software also allows separate
limits to be set for each of the packet types. Which of these options can be
implemented depends on the model of switch hardware.
By default, packet storm protection is set to none, that is, disabled. It can be
enabled, and each of the limits can be set using the command:
set switch port=port-list [bclimit={none|limit}]
[dlflimit={none|limit}] [mclimit={none|limit}]
Packet storm protection limits cannot be set for each individual port on the
switch, but can be set for each processing block of ports. The processing blocks
are sets of 8 ports (e.g. as many as are applicable of ports 1-8, 9-16 and 17-24)
and each uplink port is a further processing block. Therefore, a 16-port switch
has four processing blocks and a 24-port switch has five. The two uplink ports
are numbered sequentially after the last port, and therefore are 17 and 18 for a
16-port switch, and 25 and 26 for a 24-port switch. Only one limit can be set per
processing block, and then applies to all three packet types. Thus each of the
packet types are either limited to this value or unlimited (none).
For the Rapier G6 series switches, each port is a processing block, and therefore
packet storm protection limits can be set for each port individually.
The show switch port command displays the packet storm protection settings.
