Port Status and Basic Configuration    

Jumbo Packets 

Enabling or Disabling Jumbo Traffic on a VLAN 

Syntax: 

vlan < 

vid

 > jumbo

[ no ] vlan 

< vid > 

jumbo

Configures the specified VLAN to allow jumbo packets 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 packets through any other VLAN 
statically configured on the switch, regardless of whether the 
other VLAN is enabled for jumbo packets. 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.) 

Operating Notes for Jumbo Traffic-Handling 

■

 

ProCurve does not recommend configuring a voice VLAN to accept jumbo 
packets. Voice VLAN packets are typically small, and allowing a voice 
VLAN to accept jumbo packet traffic can degrade the voice transmission 
performance. 

■

 

You can configure the default, primary, and/or (if configured) the man­
agement VLAN to accept jumbo packets on all ports belonging to the 
VLAN. 

■

 

When the switch applies the default MTU (1522-bytes) to a VLAN, all ports 
in the VLAN can receive incoming packets of up to 1522 bytes in length. 
When the switch applies the jumbo MTU (9220 bytes) to a VLAN, all ports 
in that VLAN can receive incoming packets of up to 9220 bytes in length. 
A port receiving packets exceeding the applicable MTU drops such pack­
ets, causing the switch to generate an Event Log message and increment 
the “Giant Rx” counter (displayed by 

show interfaces < 

port-list 

>

). 

■

 

The switch does not allow flow control and jumbo packet capability to 
co-exist on a port. Attempting to configure both on the same port gener­
ates an error message in the CLI and sends a similar message to the Event 
Log. 

■

 

The default MTU is 1522 bytes (including 4 bytes for the VLAN tag). The 
jumbo MTU is 9220 bytes (including 4 bytes for the VLAN tag).
