HP MSR2000/3000/4000 Router Series Interface Command Reference

65
Parameters
mrusize: Maximum receive unit (MRU) to be set, in the range of 4 to 1700 bytes.
Usage guidelines
This command applies to only interfaces operating in asynchronous flow mode.
Examples
# Set the MRU of interface Async 6/4/0 operating in flow mode to 1500 bytes.
<Sysname> system-view
[Sysname] interface async 6/4/0
[Sysname-Async6/4/0] async-mode flow
[Sysname-Async6/4/0] phy-mru 1500
# Set the MRU of interface serial 2/0 operating in flow mode to 1500 bytes.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] physical-mode async
[Sysname-Serial2/0] async-mode flow
