Q
What is the Cisco ISR 2900 Series router?
A
The Cisco ISR 2900 Series is a modular branch router designed for enterprise WAN, security, voice and video. It delivers integrated services in a single device to simplify branch infrastructure and reduce TCO.
Q
Which models are included in the ISR 2900 Series?
A
The ISR 2900 Series includes four models: 2911, 2921, 2951 and 2951-SEC. Each model differs in throughput, slot capacity and built-in security features to suit varying branch needs.
Q
What are the key features of the ISR 2900 Series?
A
Key features include modular service slots, up to 50 Mbps throughput (2911) or 100 Mbps (2951), embedded hardware encryption, integrated Voice and UCS-E, and support for Cisco SD-WAN. These features streamline branch operations.
Q
What performance can I expect from the ISR 2900?
A
ISR 2900 routers deliver up to 100 Mbps aggregate throughput and support up to 250,000 concurrent sessions. Performance scales with performance-on-demand licenses to meet growing application demands.
Q
How many network interface modules does the ISR 2900 support?
A
ISR 2900 routers support two fixed Gigabit Ethernet ports plus two Enhanced High-Speed WAN Interface Card (EHWIC) slots. This allows flexible deployment of WAN, LAN and specialized connectivity modules.
Q
What WAN connectivity options are available on the ISR 2900?
A
The ISR 2900 supports Ethernet, T1/E1, T3/E3, VDSL2, ADSL2+, 3G/4G LTE and serial interfaces via EHWICs. This variety ensures reliable WAN access and redundancy for branch deployments.
Q
Does the ISR 2900 support advanced security features?
A
Yes. It offers embedded hardware encryption, firewall, VPN (IPsec/SSL), intrusion prevention (IPS), URL filtering and Cisco TrustSec. These features protect branch offices from evolving threats.
Q
How does the ISR 2900 handle voice and video traffic?
A
ISR 2900 routers include integrated Unified Communications and optional DSP module support for voice gateways. They also support Cisco Medianet for video optimization to deliver high-quality multimedia services.
Q
What is the power consumption of the ISR 2900 Series?
A
Power consumption ranges from 60W to 120W depending on model and module configuration. The routers support AC and optional DC power supplies with power-saving PoE+ capabilities.
Q
Which operating system does the ISR 2900 run?
A
ISR 2900 Series runs Cisco IOS Software with feature sets such as IP Base, Security, and UC. Cisco IOS provides a consistent CLI and modular code for enhanced reliability and rapid feature development.
Q
How do I upgrade the Cisco IOS on the ISR 2900?
A
Use Cisco’s ROMmon mode or the web-based Cisco Configuration Professional to upload the new IOS image via TFTP, FTP or USB. Always verify MD5 checksums and back up your configuration first.
Q
Which licenses are required for advanced features on ISR 2900?
A
Cisco offers Performance-on-Demand, Security, and Unified Communication licenses. Choose licenses based on required VPN throughput, advanced firewall, voice, video or SD-WAN capabilities.
Q
How do I configure the ISR 2900 for remote management?
A
Enable SSH, SNMPv3 and Cisco Smart Licensing on the router. Then configure management access lists, user roles and AAA to secure remote CLI and HTTPS-based Cisco Configuration Professional access.
Q
What high availability options are available for the ISR 2900?
A
The ISR 2900 supports Stateful Switchover (SSO) and Nonstop Forwarding (NSF) in multislot configurations. It also allows redundant WAN links and power supplies for enhanced uptime.
Q
What warranty and support are available for the ISR 2900?
A
Cisco provides a limited lifetime hardware warranty plus 90-day software updates. Additional SMARTnet service contracts offer 24×7 support, advance replacement and continuous OS updates.
Q
How do I choose the right ISR 2900 model for my network?
A
Assess required throughput, interface density, security and voice features. Select 2911 for small branches, 2921 for medium branches, and 2951 for high-performance security and unified communications.
Q
Can the ISR 2900 integrate with Cisco SD-WAN?
A
Yes. With the IOS XE release and SD-WAN license, ISR 2900 routers act as vSmart vEdge routers. They support overlay tunnels, centralized policy and telemetry for secure, manageable WAN fabric.
