CLI Commands for Troubleshooting

Use the following commands to provide information to help you troubleshoot installation of your SCE 1000 platform. Refer to Cisco Service Control Engine (SCE) Software Configuration Guide or the Cisco Service Control Engine (SCE) CLI Command Reference for more information.

Note Remember that if the management interface is not operational, you should connect the SCE 1000 platform to a local console so that you can enter CLI commands for troubleshooting.

Troubleshooting firmware package installation:

Boot system <filename> — Specifies and verifies the package file to be installed. Error messages or other output identify problems with the package file.

Following is a sample output from the Boot system command.

SCE 1000(config)#boot system ftp://vk:vk@10.1.1.230/downloads/SENum.pkg.pkg Verifying package file SENum.pkg.pkg…

Package file verified OK.

Troubleshooting the management subsystem:

show interface Mng — Displays IP address and auto-negotiation information for the management interfaces.

Following is a sample output from the show interface Mng command. ip address: 10.1.6.145

subnet mask: 255.255.0.0

Configured speed: auto, configured duplex: auto

AutoNegotiation is On, link is Up, actual speed: 100, actual duplex: half

show ip default-gateway — Displays the IP address of the configured default gateway.

Following is a sample output from the show ip default-gateway command.

Default gateway: 10.1.1.1

show ip route — Displays the entire routing table and the destination of last resort (default-gateway).

Following is a sample output from the show ip route command.

gateway of last resort is

10.1.1.1

show access-lists — Shows all access-lists or a specific access list.

Following is a sample output from the show access-lists command.

Standard IP access list 1

Permit 10.1.1.0, wildcard bits 0.0.0.255 deny any

show telnet — Displays the status of the telnet server daemon (status) or any active Telnet sessions (sessions).

Following is a sample output from the show telnet command.

show telnet sessions

There is 1 active telnet session:
