A Cisco router is a commonly used routing product in large and medium-sized networks. As a core router, It is the soul of the entire network. If the Administrator is improperly set, the security deployment may be taken over by attackers if it is not in place. In that case, all the networks under it will fall, and the extent of its harm is self-evident. 1. One Security Test (

controller switches and 9216 fibre channel switches Figure 1 Cisco MDS 9000 Series fibre channel switches are a new product developed by Cisco to provide outstanding performance and high port density. However, it is equally important that it can optimize the configuration of Bandwidth Resources in the storage network. The

Cisco DHCP configuration has always been our focus. We have also sorted out some materials in this regard. The following is the specific content. A company uses Cisco 3620 as the ios dhcp Server. the IP address of the fastethernet0 port connected to the Intranet is 192.168.1.4, And the L2 Switch uses two Cisco 2950, A layer-3 Switch uses a

Single-user Cisco ProductsSome products of the SOHO series use dial-up technology, such as ISDN Integrated Service data network, which allows users to roam from one place to another, or dial to the central site.The Cisco200 series for ISDN has gradually withdrawn from the market. We recommend that you upgrade it to the 700 series. The 600 series can be used with digital user line DSL) interfaces. The 800 Series features more than the 700 series, espec

quickly restored. To enable most Cisco NSF/stable restart deployment, the peer router that restarts the router must also support these extensions. This is mainly because of the following two reasons. First, RP switching does not represent topology changes, but only indicates RP recovery. A peer-to-peer router can use the smooth restart and expansion to avoid disabling external broadcast and enabling and restarting the router. This prevents unnecessar

This article introduces the configuration and operation process of IOS upgrade against Cisco routers in two ways. Not long ago, when a friend upgraded CISCO2610 with a voice mode, the memory flash of the router was 8 MB, and the IOS software was more than 7 mb. After the upgrade, the router could not start normally. Go to the rommon 1 gt; status after startup to request help. As I have been engaged in comp
