Workgroup Remote Access Switch 377S YSTEM VERIFICATIONVerifying Compression is OperationalV ERIFYING C OMPRESSION IS OPERATIONAL1. Make sure compression is enabled on a system-wide basis.2. Cause a call to be established with a device for which per-device compression is enabled.3. To verify that compression is in effect with the device, issue thecmp stats console command while the connection is in place. If compression is in effect, this commandwill display the current compression counters and ratios. If compression is not in effect, thecommand will return an indication that the device is a non-compressed connection. Ifcompression is not in effect, refer to Compression in the Problem Diagnosis chapter.V ERIFYING R ESERVED B ANDWIDTH IS O PERATIONAL1. Configure several different combinations of lines and devices.2. Attempt outbound and inbound calls.3. Verify the proper success and reject of each.If there is a problem, check the configuration of the profiles and how they are assigned to eachdevice (refer to the Bandwidth Reservation in the Configuring Call Control chapter).V ERIFYING PPP L INK F AILURE DETECTION IS O PERATIONALTo verify that Frame Relay’s Link Failure Detection is enabled, a trace can be performed to view theEcho-Request and Reply packets:1. With the feature enabled, cause a connection to be established.2. Erase the system log (issue theer command).3. Issue thetrace ppp on console command.4. Wait for at least the configured Echo Frequency.5. Display the system log (issue thedr command). If the feature is operational, some frames likethose of the following example will be seen:(I) 16:28:49.71 #C021: Conn=001 OUT-PPP:LCP ECHO REQ Id=0x50 Len=10(I) 16:28:49.71 #0000: 3E 03 78 AC(I) 16:28:49.76 #C021: Conn=001 IN -PPP:LCP ECHO RPLY Id=0x50 Len=10(I) 16:28:49.76 #0000: 70 18 D0 87(I) 16:28:59.82 #C021: Conn=001 OUT-PPP:LCP ECHO REQ Id=0x51 Len=10(I) 16:28:59.82 #0000: 3E 03 78 AC(I) 16:28:59.82 #C021: Conn=001 IN -PPP:LCP ECHO RPLY Id=0x51 Len=10(I) 16:28:59.82 #0000: 70 18 D0 87Short of having a faulty PPP link, verifying that the feature detects a failure can be accomplishedas follows:
