How to Commission the Cisco AS5850 Universal Gateway

tx_one_col_err=0, tx_more_col_err=0, tx_no_enp=0, tx_deferred_err=0

tx_underrun_err=0, tx_late_collision_err=0, tx_loss_carrier_err=0

tx_exc_collision_err=0, tx_buff_err=0, fatal_tx_err=0 tx_limited=0(0)

Note Loss of DSIP keepalive messages indicates that there is no communication between the RSC card and

the feature cards. After DSIP Hello messages succeed, the backplane Fast Ethernet connection changes

its state to Up. Until the interfaces are up, the RSC card and feature cards cannot communicate.

Caution Verify that console logging is disabled. To do so, enter the show logging command and then, if needed,

the no logging console command. If logging is enabled, the universal gateway might intermittently

freeze up as soon as the console port gets overloaded with log messages.

Messages appear on the console terminal after the feature card is physically removed from slot 12

and reinserted. Approximately 120 seconds elapse before all these messages appear.

The following boot sequence occurs in the previous example:

• The feature card takes 15 seconds to boot up. Afterward, the card checks the system inventory.

• The RSC card loads the appropriate boot images onto the feature cards.

• More than one minute elapses before the RSC card detects the first DSIP Hello message from

the first feature card (in slot 12).

• The RSC card gives the feature cards the appropriate images.

c. For advanced troubleshooting of the feature cards after the RSC card is up, open a virtual-console

session to the feature card. To end the session, enter Ctrl-C three times.
