1+1 Redundant PSUs ensure the continuous normal operation of switch.
Voice VLAN improves voice traffic transmission priority and guarantee voice quality by assigning voice traffic to a dedicated VLAN without competing with other traffic.
OSPF simplifies topologies by splitting autonomous systems into areas, automatically calculates and renews the shortest path, and transmits link status information, reducing labor hours.
