Jumbo Frames

Viewing the Current Jumbo Configuration

Syntax: show vlans

Lists the static VLANs configured on the switch and includes a Jumbo column to indicate which VLANs are configured to support inbound jumbo traffic. All ports belonging to a jumbo-enabled VLAN can receive jumbo traffic. (For more information refer to “Configuring a Maximum Frame Size” on page 12-7.) See Figure 12-1,below.

Indicates which static VLANs are configured to enable jumbo frames.

Figure 12-1. Example Listing of Static VLANs To Show Jumbo Status Per VLAN

Syntax: show vlans ports < port-list>

Lists the static VLANs to which the specified port(s) belong, including the Jumbo column to indicate which VLANs are configured to support jumbo traffic. Entering only one port in < port-list > results in a list of all VLANs to which that port belongs. Entering multiple ports in < port-list > results in a superset list that includes the VLAN memberships of all ports in the list, even though the individual ports in the list may belong to different subsets of the complete VLAN listing. For example, if port 1 belongs to VLAN 1, port 2 belongs to VLAN 10, and port 3 belongs to VLAN 15, then executing this command with a < port-list> of 1-3results in a listing of all three VLANs, even though none of the ports belong to all three VLANS. (Refer to Figure 12-2.)
