Enabling or Disabling Jumbo Traffic on a 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.
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.
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.)
Syntax: jumbo max-frame-size <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
