How the Cisco 1800 vswitch works and its skills

Cisco 1800 is another core product launched by Cisco. But can this product have a place in the market, it depends on its own performance and whether it is the type of switch the customer needs.

CISCO products are widely used by network users. understanding of their typical products and their characteristics can give a general understanding of network devices, the following describes the vro products of the Cisco1800 series, Cisco2600 series, Cisco 2800 series, Cisco 1800 switch modularization, and fixed configuration.

First, take "S26C-12007XK", "CD26-BHP-12.0.7 =" the two product models as an example to introduce the meaning of the Cisco product model name letter: Prefix: S -- pre-installed chassis, no independent media packaging, SF-pre-installed chassis, no independent media packaging, SW-floppy disk media, CD-CD media.

Intermediate: A -- Enterprise version, B -- includes IP/IPX/Apple Talk/DecNet protocol, C -- IP Only version, and D -- Desktop version, includes the IP/IPX and E -- Remote Access Server versions, which are used with multiple port dialing Access services, the H -- firewall feature version, and the P -- ip plus features, such as Easy IP, Multicast Routing, DLSw +, L -- IPSEC 56-bit encrypted version, K2 -- IPSEC 3DES encrypted ,.

This technology is currently prohibited from exporting to China, therefore, it is not allowed to order and upgrade, N -- APPN feature version, R1 -- SNA feature version, U -- Support H.323 data stream compression feature version, W -- IPSEC 40-bit encrypted version, and HY -- have IPSEC 56 bit encryption firewall feature version.

Suffix: T -- version with modification (patch), (old) XK -- version with modification (patch) (new), FL26-C-B = upgrade protocol for Cisco IOS. software upgrades with this Protocol are legal. NOTE: If multiple feature sets are supported at the same time, there are multiple letters, such as CD26-BHP-12.0.7 =.

1. Cisco 1800 vswitch Series

The Cisco 1800 series Integrated Multi-Service Router is the next generation of Cisco 1700 Series Modular and fixed configuration routers. Cisco 1801, 1802, 1803, 1811, and 1812 integrated router 1 use fixed configurations, while Cisco 1841 integrated router uses modular configurations.

Compared with the previous generation of Cisco 1700 series routers, the fixed configuration router is designed for broadband, Metro Ethernet, and wireless secure connections, it can provide significant performance improvement, function improvement, rich application and higher value. Cisco 1800 series fixed configuration routers can provide secure broadband access and multiple concurrent services for branches and small offices.

Provides integrated ISDN basic rate interface (BRI), analog modem, or Ethernet backup port for redundant WAN links and load balancing, use multiple antennas to provide a safe Wireless LAN for simultaneous 802.11a/B/g operations. Provides advanced security functions.

Including: stateful detection firewall, IP Security IPSec) Triple VPN Data Encryption Standard [3DES] or Advanced Encryption Standard [AES]), Intrusion Prevention System IPS) by implementing network access control NAC) and security access policies, provides eight ports that support VLAN and optional Ethernet Power Supply PoE, 10 Mbit/s, 100 Mbit/s, and manageable switches, provides easy deployment and remote management functions through Web-based tools and Cisco IOS software.

Cisco 1801, 1802, and 1803 routers can use an asymmetric DSLADSL) Cisco 1801) ISDN-based ADSLCisco 1802 or Symmetric high-speed DSLG. SHDSL) Cisco 1803), providing high-speed DSL broadband access.

Use integrated standby isdn s/t bri to ensure reliable network connection. Cisco 1811 and 1812 not only provide high-speed broadband or Ethernet access through two 10/100 BASE-T Fast Ethernet ports, but also through a V.92 analog modem Cisco 1811) or isdn s/t bri interface Cisco 1812) provides an integrated backup WAN connection.

The Cisco 1800 vswitch series fixed configuration routers provide powerful network infrastructure for SMBSMB-SmallMediumBusiness and small enterprise branches. They provide access to the Internet, enterprise networks, or other remote offices, while using integrated Cisco IOS software security features and features to protect critical data.

They also allow enterprises to use the same device to provide a variety of services that were normally executed by multiple devices separately. Integrated routers can provide redundant connections, LAN switches, firewalls, VPNs, IPS, wireless technologies, and service quality [QoS]), this greatly reduces costs. Cisco IOS software provides strong support for this flexibility. It can use recognized and standard Internet and dedicated WAN networking software to provide the most secure, scalable, and functional network support in the industry.
