Supervisor Engine II G has a bridge address table for up to 16,000 active Media Access Control (MAC) addresses and associated virtual LANs (VLANs) allocated dynamically between active ports. The switching engine provides data path and control for all network interfaces including modular Fast Ethernet or Gigabit Ethernet interfaces that can support redundancy using the spanning-tree algorithm or load sharing when used with VLANs. Management functions include monitoring the interface and environmental status and providing Simple Network Management Protocol (SNMP) management and the console/Telnet interface.
