Huawei router and the same class Cisco router in the functional characteristics and configuration interface is completely consistent, some aspects also according to the needs of domestic users made a good improvement. For example, in English and Chinese can be switched configuration and debugging interface, so that use

192.168.61.128 as the remote server IP address of GNS3, perhaps everyone is more curious about the configuration of the address there is no need to pay attention to the place, the answer is there, as long as the IP address to the IOU virtual machine IP address.In fact, this place is currently reserved for IOU settings. You can simply think that GNS3 can not only use the local dynamips as iOS running server, it can also designate a remote UNIX virtual

understanding the Spanning Tree principle, we can have a specific purpose. The command to reconfigure the Cisco router is as follows: DispatchA # config terminal ! Select the ieee stp Spanning Tree Protocol. DispatchA (config) # bridge 1 protocol ieee ! Select the router at the master scheduling end as the root bridge. DispatchA (config) # bridge 1 priority 0 DispatchA (config) # interface ethernet0/0 DispatchA (config-if) # bridge-g

management address, which is disabled by default and needs to be opened manually. The permission levels on Cisco devices are from 0 ~ 15. The default Telnet mode is 1, and the maximum permission is 15. (Privilege level [0-15]) The login function is enabled for the vty line by default, which means you must set a password for it to log on. Password 7 ***** cannot be used to set plain text. For example, if yo

With the development of the routing industry, the market demand is more extensive, but many users still do not understand the routing configuration issues. Here we mainly provide a comprehensive description of the Cisco router NAT configuration. More and more INTERNET resource sharing methods are available. In most cases, ddnleased lines are widely used with thei

, reducing network complexity and improving server management capabilities and large-scale scalability. Each UCS rack server is equipped with a VIF interface card that provides two Gigabit Ethernet interfaces. using Cisco Network virtualization technology, it provides both management network interfaces and operating system network interfaces. FI is the old version of 6120, which is inconsistent with the new server version. Therefore, you need to set a

Overview of LAN switches LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's Catalyst 5000 Series LAN switch as an example. It includes an integrated switching hardware structure, 10-Mbps Ethernet that supports switching, and-Mbps Fast Ethernet, supports fast Ethernet, FDDI, exchange-type ring, and layer-3 switching processing. This type of switch can provide exchange access to workstations,

following example:Example 1. Pix525 (config) # fixup protocol ftp 21Enable the ftp protocol and specify the ftp port number as 21.Example 2. Pix525 (config) # fixup protocol http 80Pix525 (config) # fixup protocol http 1080Specify port 80 and port 1080 for the http protocol.Example 3. Pix525 (config) # no fixup protocol smtp 80Disable the smtp protocol. D. Set telnetTelnet has a version change. Before the pix OS 5.0 (the version number of the pix ope

Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging the server is not allowed. In this case, an

. Setting up TelnetTelnet has a version of the change. Before the PIX OS 5.0 (the version number of the PIX OS), the PIX can only be accessed via Telnet from hosts on the internal network. In PIX OS 5.0 and later versions, Telnet to PIX Access can be enabled on all interfaces. When you want to telnet to the PIX firewall from the external interface, the Telnet traffic needs to be protected with IPSec, which means that the user must configure the PIX to establish an IPSec tunnel to another pix, ro

principle, using a Udpecho request instead of a ICMPECHO request to initiate an attack. While cyber security experts are focused on developing devices that block Dos attacks, they have little effect because Dos attacks exploit the weaknesses of the TCP protocol itself. Properly configured routers can effectively prevent Dos attacks. In Cisco routers, for example, the iOS software in

can run normally. However, it makes sense to rename a vro and uniquely identify it. Example: Router (config) # hostname Router-Branch-23 In addition, you can configure a domain name on the router so that it knows which DNS domain it is in. Example: Router-Branch-23 (config) # ip domain name TechRepublic.com 3. Set a password for privileged Mode When talking about setting a password to enter the privileged

complete, you can use the "show vlan #" command to display a specific vlan information and verify VLAN parameters. For example:Switch # show vlan 3 2. configuration of multiple switchesTo allow a VLAN to span multiple switches, you must configure the trunk (trunk) to connect to these switches. Cisco requires that trunk protocols such as ISL be used on such trunk links, so the command to enable trunk protoc

The following is a brief description of the configuration steps of 5505:1. Supervisor Engine Software Configuration:First, the Supervisor Engine Module needs an in-band (sc0) interface IP address, which is a manageable address and can be managed by telnet or SNMP for 5505. There is also an SLIPsl0 interface, which is not commonly used and is not described here.The default IP address of sc0 is 0.0.0.0, which belongs to vlan1. VLAN1 is the default VLAN
