• Availability and redundancy:

• Virtual Router Redundancy Protocol (VRRP) for Layer 3 router redundancy
• IEEE 802.1D Spanning Tree Protocol (STP) for providing L2 redundancy
• IEEE 802.1s Multiple STP (MSTP) for topology optimization, up to 32 STP instances are supported by single switch
• Layer 2 Trunk Failover to support active/standby configurations of network adapter teaming on blades
• Server Load Balancing provides load distribution among servers in farm and automatic failover of user sessions in case of application failure
• Real server health check for server or application status and content availability
• Interchassis redundancy (L2 and L7)

• VLAN support:

• Up to 1024 VLANs supported per switch, with VLAN numbers ranging from 1 to 4095 (4095 is used for management module’s connection only)
