8.5.4 Checking the configuration
Run the following commands to check the previous configuration.
Action Command
Check statistics about FR LMI
packets.
display fr lmi-info [ interface interface-type
interface-number ]
Run the display fr lmi-info command. When statistics about FR LMI packets appear the
configuration succeeds. For example:
<Nortel> display fr lmi-info
Frame relay LMI statistics for interface MFR6/0/0 (DTE, Q933)
T391DTE = 10 (hold timer 10)
N391DTE = 5, N392DTE = 3, N393DTE = 4
out status enquiry = 0, in status = 0
status timeout = 0, discarded messages = 0
Frame relay LMI statistics for interface Serial6/0/0 (DCE, Q933)
T392DCE = 15, N392DCE = 3, N393DCE = 4
in status enquiry = 250, out status = 250
status enquiry timeout = 0, discarded messages = 15
8.6 Configuring frame relay switching
8.6.1 Establishing the configuration task
Applicable environment
When data exchange is required on a FR switch, you need to configure the FR switching
function.
You can use a router to implement the FR switching, which you can configure by the FR
switching route and the FR switching PVC.
