Description
Remote Management and Monitoring
Cisco 2811 SRST/K9 is a voice bundle that includes a Cisco 2811 router, PVDM2-16 (Packet Voice Digital Signal Processor) and SRST (Survivable Remote Site Telephony) software. This bundle is designed for remote office environments and provides call processing and voice mail support in the event of a WAN failure.
To manage and monitor the Cisco 2811 SRST/K9, you can use the Cisco IOS command-line interface (CLI) to configure and troubleshoot the device. Additionally, you can use Cisco’s Network Assistant or other network management software to remotely manage and monitor the device.
The SRST feature allows you to configure a Cisco IOS router to serve as a primary call-processing agent for IP phones in the event that the connection to the Cisco Unified Communications Manager (UCM) is lost.
The PVDM2-16 is used to provide voice compression and conferencing capabilities. The FL (Flash) and SRST36 (Software) licenses also provide additional features such as storage and call processing.
The SP Services (Security and VPN Services) is used to secure the network and encrypt the data traffic.
Network Segmentation and Access Control
Network segmentation and access control are essential for securing any network, including the CISCO2811-SRST/K9 Cisco 2811 Voice Bundle.
One way to segment the network is by using VLANs (Virtual LANs). This allows you to create multiple logical networks on a single physical network, which can be used to separate different types of traffic, such as voice and data.
Another way to segment the network is by using Access Control Lists (ACLs) to control access to different parts of the network. ACLs can be used to restrict access to certain network resources based on IP addresses, protocols, and ports.
You can also use Cisco’s Integrated Services Router (ISR) security features such as Firewall, VPN, and intrusion prevention to secure the network. These features can be used to protect the network from external threats, such as hackers and malware.
Additionally, you can use Cisco’s Security Manager to centrally manage and monitor the security features on the device, and to apply security policies across the network.
Troubleshooting and Maintenance
Troubleshooting and maintenance are important aspects of maintaining the CISCO2811-SRST/K9 Cisco 2811 Voice Bundle.
To troubleshoot any issues with the device, you can use the Cisco IOS command-line interface (CLI) to view the device’s configuration, status, and log messages. Some common troubleshooting commands include:
- show running-config: Displays the current running configuration of the device
- show ip interface brief: Displays a summary of the IP interfaces and their status
- show logging: Displays the contents of the device’s system log
- show call active voice: Displays the active voice calls
- debug voice call: Displays detailed information about the voice call
You can also use Cisco’s Network Assistant or other network management software to remotely monitor the device and troubleshoot any issues.
To maintain the device, it’s important to keep the Cisco IOS software version up to date, by regularly checking for updates and upgrading the device as necessary. Additionally, you should regularly back up the device’s configuration and test the backup to ensure it can be restored properly.
It’s also important to check the device’s memory and disk usage and take action when needed. You can use the show memory and show disk commands to check the usage.
