Dear All, My router is having problem in switching back to primary interface. Primary interface is E1 and serial interface is backuped by BRI interface. The serial interface becomes active again only after giving the commands "shutdown" and "no shutdown" or restarting the router. What are the other debug commands to find the possible reason for this strange behaviour ? Any help will be appeciated. Following is output of "debug backup" pan_2503#debug backup Backup events debugging is on pan_2503# 1d11h: %LINK-3-UPDOWN: Interface Serial1, changed state to down 1d11h: BACKUP(Serial1): event = primary went down 1d11h: BACKUP(Serial1): changed state to "waiting to backup" 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1, changed state to down 1d11h: BACKUP(Serial1): event = timer expired 1d11h: %LINK-3-UPDOWN: Interface BRI0:1, changed state to down 1d11h: %LINK-3-UPDOWN: Interface BRI0:2, changed state to down 1d11h: BACKUP(Serial1): secondary interface (BRI0) made active 1d11h: BACKUP(Serial1): changed state to "backup mode" 1d11h: %LINK-3-UPDOWN: Interface BRI0, changed state to up 1d11h: %ISDN-6-LAYER2UP: Layer 2 for Interface BR0, TEI 87 changed to up 1d11h: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up 1d11h: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1, changed state to up 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access1, changed state to up 1d11h: %LINK-3-UPDOWN: Interface BRI0:2, changed state to up 1d11h: %ISDN-6-CONNECT: Interface BRI0:1 is now connected to 95118002256 gur_3660 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:2, changed state to up 1d11h: %ISDN-6-CONNECT: Interface BRI0:2 is now connected to 95118002256 gur_3660 pan_2503# pan_2503# 1d11h: %LINK-3-UPDOWN: Interface Serial1, changed state to up 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1, changed state to up 1d11h: BACKUP(Serial1): event = primary came up 1d11h: BACKUP(Serial1): changed state to "waiting to revert" 1d11h: BACKUP(Serial1): event = timer expired 1d11h: %LINK-3-UPDOWN: Interface BRI0:1, changed state to down 1d11h: %LINK-3-UPDOWN: Interface BRI0:2, changed state to down 1d11h: BACKUP(Serial1): secondary interface (BRI0) moved to standby 1d11h: BACKUP(Serial1): changed state to "normal operation" 1d11h: %LINK-5-CHANGED: Interface BRI0, changed state to standby mode 1d11h: %LINK-3-UPDOWN: Interface BRI0:1, changed state to down 1d11h: %LINK-3-UPDOWN: Interface BRI0:2, changed state to down 1d11h: %ISDN-6-DISCONNECT: Interface BRI0:1 disconnected from unknown , call la sted 91 seconds 1d11h: %ISDN-6-DISCONNECT: Interface BRI0:2 disconnected from unknown , call la sted 89 seconds 1d11h: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BRI0, TEI 87 changed to down 1d11h: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BR0, TEI 87 changed to down 1d11h: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to down 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1, changed state to down 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:2, changed state to down 1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access1, changed state to down pan_2503# pan_2503#conf pan_2503#configure t pan_2503#configure terminal Enter configuration commands, one per line.
