    Cisco WS-X5239-RJ21 Miscellaneous

    Additional Information: Frame Processing:
  • Transparent bridging (802.1d)

    Key Feature Summary:
  • Broadcast Suppression
  • ISL
  • 802.IQ/P
  • Ether- Channel
  • Inline Rewrite
  • 802.3x Flow Control
  • WRED

  • IGMP snooping for fast joins and leaves on multicast groups
  • Protocol filtering to minimize unnecessary traffic by protocol type (such as block IPX and SAP and RIP broadcasts for IP-only clients)
  • Port security to control access and keep unauthorized users off the network
  • Dynamic VLANs for automatic VLAN assignment based on user login identity or host MAC address
  • QoS with trilevel priority queues on the switching backplane
  • Supports any combination of switching modules; modules can be hot-swapped or added as needed without resetting the switch
  • Connectivity from switched Ethernet and Fast Ethernet to Fiber Distributed Data Interface (FDDI), Gigabit Ethernet, and ATM backbones
  • Wire-speed performance on the Ethernet and Fast Ethernet interfaces
  • Superior traffic management with large interface buffers to accommodate bursty traffic
  • Four groups of RMON on each port
  • Supports multiple active MAC addresses (up to 16,000) per port
  • Supports spanning-tree algorithm on logical VLANs for fault-tolerant connectivity
  • Capability for any backbone Fast Ethernet interface to support up to 1000 VLANs between Catalyst 5000 Family switching platforms and Cisco routers
  • Supports broadcast, multicast, and unicast suppression
  • Supports IEEE 802.3u autonegotiation process that allows the switch to negotiate speed (10 or 100 Mbps) or duplex mode (half or full duplex) with an attached device
  • Autosenses speed and duplex mode if the attached device dCEs not negotiate with the switch
  • Uplink fast convergence for rapid STP convergence on wiring closet uplinks
  • Backbone fast convergence for optimum STP convergence in backbone
  • Compatibility:
    • Catalyst 5000 and 5500 Family switches
    • Catalyst 5000 and 5500 Family switches
