0916 287 068 Integrated Services Router CISCO C891F-K9
Integrated Services Router CISCO C891F-K9
- Cisco 891F Gigabit Ethernet security router with SFP.
- WAN Interfaces: 1-port GE or 1‑port SFP, 1-port FE.
- LAN Interfaces: 8-port 10-/100-/1000-Mbps managed switch (4‑ports PoE capable with 125W power supply adapter).
Features
- Redundant WAN connections for failover protection and load balancing.
- Dynamic failover protocols such as Virtual Router Redundancy Protocol (VRRP; RFC 2338), Hot Standby Router Protocol (HSRP), and Multigroup HSRP (MHSRP).
- Dial backup with external modem through a virtual auxiliary port.
- The router can run multiple services simultaneously with no performance degradation.
- Network perimeter security with integrated application inspection firewall.
- Data privacy through high-speed IP Security (IPsec) Triple Data Encryption Standard (3DES) and Advanced Encryption Standard (AES) encryption.
- Enforced security policy with intrusion prevention.
- Security hardware acceleration.
- FlexVPN.
- Next-generation encryption for secure network communications systems, reliable for the next decade.
- Cisco ISR Web Security with Cisco ScanSafe, designed to prevent zero-day malware from reaching corporate networks.
- Supports LAN connections, both Ethernet and Wi-Fi, in one appliance. Contains an integrated 802.11n WLAN access point that supports both autonomous and unified modes, as well as an 8-port LAN switch. Management of both the wired and wireless environments is integrated.
- Simplifies and centralizes configuration and management of wireless and wireline devices. Supports WLAN services without requiring a wireless LAN controller.
- Supports separate console, auxiliary, and USB ports.
- Provides one USB 2.0 flash memory.
