R0106-HP MSR Router Series Interface Command Reference(V7)

67
Parameters
mrusize: Sets the maximum receive unit (MRU). The value range for this argument is 4 to 1700 bytes.
Usage guidelines
This command applies only to interfaces operating in asynchronous flow mode.
Examples
# Set the MRU of Async 2/4/0 operating in flow mode to 1500 bytes.
<Sysname> system-view
[Sysname] interface async 2/4/0
[Sysname-Async2/4/0] async-mode flow
[Sysname-Async2/4/0] phy-mru 1500
# Set the MRU of Serial 2/1/0 operating in flow mode to 1500 bytes.
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] physical-mode async
[Sysname-Serial2/1/0] async-mode flow
[Sysname-Serial2/1/0] phy-mru 1500
