BCM56320B1IFSBG Product Details

The BCM56320B1IFSBG switching processor chip supports 12 Gigabit ports and one 10-Gigabit uplink with all ports in wirespeed operation. The BCM56320B1IFSBG is ideal for applications such as multi-Gigabit port switches or aggregating multiple-Gigabit ports to a 10-Gigabit backplane. 

 For Gigabit ports, the BCM56320B1IFSBG supports PCS (802.3z, 1000BASE-X) or GMII (802.3ab, 1000BASE-T) interfaces with full-duplex operation at Gigabit speed, and full- or halfduplex operation at 10/100 Mbps speed (using 1000BASET). For the uplink port, the BCM56320B1IFSBG supports XGMII. The BCM56320B1IFSBG supports 802.1Q VLAN tagging as an option (Qon). 

The BCM56320B1IFSBG supports 802.1v VLAN Classification by Protocol. There are four user-programmable protocols that can be set up per port by the VLAN Classification EtherType and the VLAN Priority/TAG registers. 

The BCM56320B1IFSBG supports both port-based and tagged (802.1q and 802.3ac) Virtual LAN (VLAN). The BCM56320B1IFSBG also supports 4K VLAN addresses with the 802.1s Multiple Spanning Tree option, and flexible and programmable ingress and egress checking rules for VLAN processing.
