[no] rpr-ieee protection pref jumbo
Use this command to set the IEEE 802.17b based RPR station MTU preference to jumbo Ethernet
frames. If all stations on the ring select jumbo preference, the ring MTU is 9,000 bytes; otherwise, it is
1,500 bytes. Use the no form of this command to select normal MTU preference.
Syntax Description
This command has no arguments or keywords.
Defaults The default is jumbo preference: not set (that is, the ring does not support jumbo frames).
Command Modes IEEE 802.17b based RPR interface configuration
Usage Guidelines
Jumbo frame support would be enabled to support frames larger than the standard Ethernet MTU of
1518 bytes across the IEEE 802.17b based RPR ring. In this command, protection can be shortened to
prot.
Examples In this example, interface is shortened to int.
Router(config)# int rpr-ieee 0
Router(config-if)# rpr-ieee prot pref jumbo
