Which models are included in the ISR 2900 Series?
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.
What are the key features of the ISR 2900 Series?
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.
What performance can I expect from the ISR 2900?
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.
How many network interface modules does the ISR 2900 support?
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.
What WAN connectivity options are available on the ISR 2900?
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.
Does the ISR 2900 support advanced security features?
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.
How does the ISR 2900 handle voice and video traffic?
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.
What is the power consumption of the ISR 2900 Series?
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.
Which operating system does the ISR 2900 run?
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.
How do I upgrade the Cisco IOS on the ISR 2900?
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.
Which licenses are required for advanced features on ISR 2900?
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.
How do I configure the ISR 2900 for remote management?
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.
What high availability options are available for the ISR 2900?
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.
What warranty and support are available for the ISR 2900?
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.
How do I choose the right ISR 2900 model for my network?
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.
Can the ISR 2900 integrate with Cisco SD-WAN?
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.
