     The switch provides more efficient large sequential data transfers by supporting jumbo frames up to 9000 bytes. Compared to standard Ethernet frames that run only up to 1500 bytes, using jumbo frames significantly reduces the per-packet overhead required to process protocol encapsulation fields.  To use jumbo frames, both the source and destination end nodes (such as a computer or server) must support jumbo frames.

  • Page 59: Class Of Service

    Console(config)#bridge-ext gvrp   Console(config)# Class of Service  Class of Service (CoS) allows you to assign priority to data packets when traffic in the switch is buffered due to congestion. This switch supports CoS by using four priority queues for each port. Data packets in a port's high-priority queue will be transmitted before packets in the lower-priority queues.  The Class of Service page allows you to set the default priority for each port or trunk, and to configure the mapping of frame priority tags to the switch's four priority queues.

  • Page 60: Traffic Classes

      Console(config)#interface ethernet 1/3   Console (config-if)#switchport priority default 5 Trunk Settings  On the Trunk Settings page, you can specify the default port priority for each port in a switch trunk.

This capability provides a highly efficient architecture for establishing VLANs within a network and for controlling broadcast/ multicast traffic between workgroups.

     In the VLAN Membership page, if a U is assigned to a port and VLAN, packets leaving the switch from that port and VLAN are untagged. If a T is assigned to a port and VLAN, packets leaving the switch from that port and VLAN are tagged with the respective ID for the VLAN to which that port belongs.

  • Page 86: Vlan Examples

    VLAN Examples  The following two examples demonstrate typical web-interface VLAN configurations for the switch.  Example 1 demonstrates a simple two-group VLAN setup.  Example 2 demonstrates a more elaborate setup, illustrating all possible scenarios for a comprehensive understanding of tagged VLANs. Example 1  Example 1 illustrates a simple two-group VLAN setup.

  • Page 93  In the preceding figure, the management VLAN is different on each switch, with the Layer 3 switch interconnecting the VLANs. The ports that interconnect the switches are configured as tagged ports. The ports on the Layer 3 switch that connect to the other switches must be configured as members of the management VLAN for each switch.
