Port Traffic Controls Jumbo Frames Enabling or Disabling Jumbo Traffic on a VLAN Syntax: vlan < vid > jumbo [no] vlan < vid > jumbo Configures the specified VLAN to allow jumbo frames on all ports on the switch that belong to that VLAN. If the VLAN is not already configured on the switch, vlan < vid > jumbo also creates the VLAN. Note that a port belonging to one jumbo VLAN can receive jumbo frames through any other VLAN statically configured on the switch, regardless of whether the other VLAN is enabled for jumbo frames. The [no] form of the command disables inbound jumbo traffic on all ports in the specified VLAN that do not also belong to another VLAN that is enabled for jumbo traffic. In a VLAN context, the command forms are jumbo and no jumbo. (Default: Jumbos disabled on the specified VLAN.) Configuring a Maximum Frame Size You can globally set a maximum frame size for Jumbo frames that will support values from 1518 bytes to 9216 bytes for untagged frames. Syntax: jumbo max-frame-size Sets the maximum frame size for Jumbo frames. The range is from 1518 bytes to 9216 bytes. Note: The jumbo max-frame-size is set on a GLOBAL level. Default: 9216 bytes SNMP Implementation Jumbo Maximum Frame Size. The maximum frame size for Jumbos is supported with the following propri etary MIB object: hpSwitchMaxFrameSize OBJECT-TYPE This is the value of the global max-frame-size supported by the switch. The default value is set to 9216 bytes. 12-25
