406 CHAPTER 22: FRAME RELAY CONFIGURATION COMMANDS
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] mfr timer ack 6
mfr timer hello
Syntax mfr timer hello seconds
undo mfr timer hello
View Frame relay interface view
Parameter seconds: Interval (in seconds) for a bundle link to send hello message, in the range
1 to 180.
Description Use the
mfr timer hello command to set the interval for a frame relay bundle
link to send hello message.
Use the
undo mfr timer hello command to restore the default.
By default, the interval for a frame relay bundle link to send hello message is 10
seconds.
Only after the link-protocol fr mfr command is used to associate a frame relay
bundle link interface with a frame relay bundle, can this command be configured.
Example # Set the bundle link Serial 2/0 to send hello message once every 15 seconds.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] mfr timer hello 15
mfr window-size
Syntax mfr window-size number
undo mfr window-size
View MFR interface view
Parameter number: Number of fragments, in the range 1 to 16.
Description Use the
mfr window-size command to configure the number of fragments that
can be hold by the window used in sliding window algorithm when multilink
frame relay reassembles received fragments.
Use the
undo mfr window-size command to restore the default.
By default, the size of a sliding window is equal to the number of physical
interfaces of an MFR bundle.
