Q
What is the Cisco ISR 1100 Series router?
A
Cisco ISR 1100 Series routers are compact, secure edge devices designed for small to medium branch offices, integrating routing, security, and wireless services in a single platform.
Q
What performance levels does the ISR 1100 Series deliver?
A
The ISR 1100 Series delivers up to 85 Mbps aggregate throughput with hardware-accelerated encryption and up to 500 kpps forwarding performance for WAN resiliency.
Q
Which network interfaces are supported by the ISR 1100?
A
ISR 1100 routers provide multiple Gigabit Ethernet ports, optional SFP slots, built-in 3G/4G LTE modules, and USB ports for WAN failover.
Q
Does the Cisco ISR 1100 support IPv6?
A
Yes. The ISR 1100 Series fully supports IPv6 routing, IPv6 ACLs, IPv6 multicast, and IPv6 transition mechanisms for end-to-end connectivity.
Q
What built-in security features does the ISR 1100 offer?
A
ISR 1100 includes integrated Cisco IOS Firewall, IPsec/SSL VPN, intrusion prevention (IPS), secure boot, and zone-based policies for comprehensive branch security.
Q
How do I configure VPN on the Cisco ISR 1100?
A
Use the Cisco IOS CLI to define ISAKMP policies, create crypto maps or tunnel interfaces, assign IPsec profiles, and apply them to the WAN interface for secure VPN tunnels.
Q
Can the ISR 1100 support Cisco SD-WAN solutions?
A
Yes. The ISR 1100 Series is Cisco SD-WAN ready, offering centralized orchestration, dynamic path selection, and policy-based routing for optimized WAN performance.
Q
How many concurrent sessions can the ISR 1100 handle?
A
Depending on model and licensing, the ISR 1100 Series supports up to 75,000 concurrent sessions to meet high user and application demands.
Q
What power supply options are available for the ISR 1100?
A
ISR 1100 routers ship with an internal AC power supply and offer optional 12 V DC input; select models also provide Power over Ethernet (PoE/PoE+).
Q
How do I update the firmware on my Cisco ISR 1100?
A
Upload the new Cisco IOS image via TFTP, FTP, or USB to flash, set the boot variable to the new image filename, and reload the router to apply the update.
Q
What are the main differences between ISR 1100 models?
A
Models 1111, 1121, and 1140 differ in throughput (25–85 Mbps), port count, PoE capabilities, and optional LTE or SFP configurations to fit branch needs.
Q
Does the ISR 1100 support Power over Ethernet?
A
Yes. Select ISR 1100 models provide PoE (up to 60 W) or PoE+ (up to 120 W) on designated Gigabit Ethernet ports for IP phones and access points.
Q
How do I enable high availability on the ISR 1100?
A
Implement Cisco IOS HSRP or VRRP for control-plane redundancy and configure dual WAN links with Performance Routing (PfR) for data-plane resilience.
Q
What licensing options are available for the Cisco ISR 1100 Series?
A
ISR 1100 offers feature tiers—SEC for advanced security, APPX for application hosting, and UC for unified communications—delivered via Cisco Smart Licensing.
Q
How can I manage and monitor my Cisco ISR 1100 router?
A
Manage ISR 1100 using Cisco DNA Center, Cisco Prime Infrastructure, or the IOS CLI; monitor via SNMP, NetFlow, and Embedded Event Manager for proactive alerts.
