CLI Commands for Troubleshooting

Use the following commands to provide information to help you troubleshoot installation of your SCE 2000 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 2000 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 2000(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:

SCE 2000 4xGBE specifications

The Cisco Systems SCE 2000 4xGBE is a robust solution designed to optimize IP networks and enhance service delivery. As a member of Cisco's Service Control Engine (SCE) product line, this device is particularly suited for service providers looking to manage network traffic, improve service quality, and provide a suite of advanced management features.

One of the standout features of the SCE 2000 is its ability to process and analyze network traffic in real-time. This capability allows operators to gain insights into user behavior, application usage, and overall network performance. By utilizing deep packet inspection technology, the SCE 2000 can identify different types of traffic, enabling network managers to enforce policies and prioritize critical applications effectively.

In terms of interface capabilities, the SCE 2000 offers four 1 Gigabit Ethernet (GbE) ports. This versatility allows for easy integration into existing network infrastructure while ensuring ample bandwidth for data transfer. The device supports both IPv4 and IPv6 protocols, making it future-proof and suitable for evolving network demands.

One of the significant technologies employed by the SCE 2000 is Service Level Agreement (SLA) management. This feature ensures that service providers can meet their commitments to customers by monitoring performance metrics such as latency, jitter, and packet loss. The ability to generate reports based on SLA compliance allows for better customer engagement and transparency.

Additionally, the SCE 2000 facilitates dynamic resource allocation, enabling service providers to adapt network resources based on current demand. This elasticity is crucial in managing peak loads and ensuring a seamless user experience. Furthermore, the device’s support for Quality of Service (QoS) policies ensures that critical applications receive the necessary bandwidth and resources dedicated to maintaining operational efficiency.

The SCE 2000 also emphasizes security with features such as intrusion detection and prevention capabilities, helping protect the integrity of the network. This combination of performance monitoring, traffic management, and security makes the SCE 2000 an invaluable tool for service providers.

In conclusion, the Cisco Systems SCE 2000 4xGBE is a powerful network management solution that excels in providing real-time traffic management, SLA compliance, and security features. Its capabilities make it an essential component for service providers aiming to optimize their networks while delivering high-quality services to their customers.
