Configuring Jumbo Frame Support
These sections describe jumbo frame support:
• Understanding Jumbo Frame Support, page 9-10
• Configuring MTU Sizes, page 9-12
Caution The following switching modules support a maximum ingress frame size of 8,092 bytes:
• WS-X6516-GE-TX when operating at 100 Mbps
• WS-X6148-RJ-45, WS-X6148-RJ-45V and WS-X6148-RJ21, WS-X6148-RJ21V
• WS-X6248-RJ-45 and WS-X6248-TEL
• WS-X6248A-RJ-45 and WS-X6248A-TEL
• WS-X6348-RJ-45, WS-X6348-RJ45V and WS-X6348-RJ-21, WX-X6348-RJ21V
When jumbo frame support is configured, these modules drop ingress frames larger than 8092 bytes.
Note The WS-X6548-GE-TX, WS-X6548V-GE-TX, WS-X6148-GE-TX, and WS-X6148V-GE-TX do not
support jumbo frames.
Understanding Jumbo Frame Support
These sections describe jumbo frame support:
• Jumbo Frame Support Overview, page 9-10
• Ethernet Ports, page 9-11
• VLAN Interfaces, page 9-12
Jumbo Frame Support Overview
A jumbo frame is a frame larger than the default Ethernet size. You enable jumbo frame support by
configuring a larger-than-default maximum transmission unit (MTU) size on a port or VLAN interface
and configuring the global LAN port MTU size.
