Port Extenders
The port extenders (PEs) provide a data path between end hosts and the control bridge and use LLDP to advertise 802.1BR capabilities to the CB over the upstream port or LAG. If capabilities match, the PE uses CSP to attach to the CB. The PE reports the number of available ports to the CB, and the CB allocates an ECID for each PE port. The PE units perform hardware-based multicast and broadcast replication.
The Ruckus ICX 7250 and ICX 7450 act as port extender units, which are managed by the control bridge. All ICX 7150 models can be configured as PE units beginning with FastIron 08.0.70 and later.
PE units rely on the CB for most network functions.
The ICX 7450 has six different models based on port density, PoE capability, and port type; in addition, each of the models supports four different flex modules. The ICX 7450 has the following models:
The ICX 7250 has the following models:
The ICX 7150 has the following models:
Note: ICX 7150 devices require a PoD license for ports that will be used for 10-Gbps connections. The exception is the ICX 7150-48XP model
, which is shipped with two 10-Gbps ports but requires a PoD license for any additional 10-Gbps connections.Note: The ICX 7150 uses trust-based licenses. Refer to the Ruckus FastIron Software Licensing Guide for information on installing ICX 7150 licenses.
Sometimes 24G is reffered as 24L.
