Enabling the debug environment

To access the debug environment, log in using the default super (super-user) profile.

For example: admin> auth super

Password:

The default password for this account is Ascend . If the password has not been changed, you should change it now to prevent unauthorized super-user access to the system.

The debug environment contains many hidden commands and parameters that are not intended for general use. The debug environment is not supported, and the documentation provided here is not comprehensive.

Caution Under most circumstances, debug commands are not required for monitoring Stinger IP DSLAM operations, and under some circumstances, these commands might produce undesirable results. Use the information with caution.

Command element

-v

-i [-u/d]

-n

-s

Description

Show gmac version.

With no additional option, initialize/reset the

GigE port.

-i -u Force GigE link up.

-i -d Force GigE link down.

Command element

-l [-i/e/d/p]

-p

-r

-w

-d [-c/a/e]

-t

-?

Description

Loopback.

-l -i Set port for internal loopback.

-l -e Set port for external loopback.

-l -d Set port for no loopback

-l -p Run loopback test for Ethernet poweron self test (POST).

Ping test.

Read a PHY register.

Write to a PHY register.

With no additional option, display all statistics.

-d -c Clear GMAC statistics.

-d -a Display ATM statistics.

-d -e Display Ethernet statistics.

Set debug level (0 through 3).

Display a summary of commands.

Example The gmac -n command sets up the network processor for communication with the GMAC port: super> gmac -n

NP setup for gmac done.

Example The gmac -s command sets up a SAR channel for communicating with the

GMAC port: super> gmac -s

GMAC: SAR conn. open with vpi = 0, vci = 200

Example The gmac -v command displays the GMAC version: super> gmac -v

GMAC version : 0x0b

Example The gmac -i command resets the Gigabit Ethernet port: super> gmac -i gigE port reset.

Example The gmac -d command displays the total transmit and receive statistics for the GigE interface of the IP control module. For details about the gmac -d output

fields, see the descriptions of MIB objects in “Total transmit statistics” on page A-30

and “Total receive statistics” on page A-32. For example, the following command

displays the current GMAC statistics: super> gmac -d

Gigabit Ethernet port statistics : txOctetsLow = 1040 txOctetsHigh = 0 txGoodPackets = 4
