Port Status and Basic Configuration
Jumbo Frames
You can enable inbound jumbo frames on a per-VLAN basis. That is, on a VLAN
configured for jumbo traffic, all ports belonging to that VLAN and
operating
at 1 Gbps or 10 Gbps allow inbound jumbo frames of up to 9220 bytes.
(Regardless of the mode configured on a given jumbo-enabled port, if the port
is operating at only 10 Mbps or 100 Mbps, only frames that do not exceed 1522
bytes are allowed inbound on that port.)
Terminology
Jumbo Frame:
An IP frame exceeding 1522 bytes in size. The maximum
Jumbo frame size is 9220 bytes. (This size includes 4 bytes for the VLAN
tag.)
Jumbo VLAN:
A VLAN configured to allow inbound jumbo traffic. All ports
belonging to a jumbo and operating at 1 Gbps or higher can receive jumbo
frames from external devices.
MTU
(
Maximum Transmission Unit)
: This is the maximum-size IP frame
the switch can receive for Layer 2 frames inbound on a port. The switch
allows jumbo frames of up to 9220 bytes.
Standard MTU:
An IP frame of 1522 bytes in size. (This size includes 4 bytes
for the VLAN tag.)
Operating Rules
■
Required Port Speed:
Allows inbound and outbound jumbo frames on
ports operating at speeds of 1 gigabit or higher. At lower port speeds, only
standard (1522-byte or smaller) frames are allowed, regardless of the
jumbo configuration.
■
Flow Control:
Disable flow control (the default setting) on any ports or
trunks through which you want to transmit or receive jumbo frames.
Leaving flow control enabled on a port can cause a high rate of jumbo
drops to occur on the port.
■
GVRP Operation:
A VLAN enabled for jumbo traffic cannot be used to
create a dynamic VLAN. A port belonging to a statically configured, jumbo-
enabled VLAN cannot join a dynamic VLAN.
■
Port Adds and Moves:
If you add a port to a VLAN that is already
configured for jumbo traffic, the switch enables that port to receive jumbo
traffic. If you remove a port from a jumbo-enabled VLAN, the switch
disables jumbo traffic capability on the port only if the port is not currently
a member of another jumbo-enabled VLAN. This same operation applies
to port trunks.
