The implementation of the multi-port Cisco switch module is a common problem. How to configure the Cisco switch module, any problems related to ports will be fully resolved in this article. Cisco

security, management, and integrated Cisco IOS features CISCO switch 2950 has several unusual features to improve network performance, manageability, and security. Network administrators can configure up to 64 virtual VLAN VLANs for each vswitch) to achieve higher data security and enhanced LAN performance. This ensur

found again. This time it is smaller. It is disconnected when it is uploaded to 16 Mb. The system still prompts timeout and write error. After careful analysis, we finally found the key to the Cisco switch failure. Two transmissions, 32 MB at a time and 16 MB at a time. Even the number of bytes is not bad, it is certainly not a problem with the transmission line. After checking the information, TFTP (Trivi

be built, while CD signals often exist. In addition, if one end of the X.25 line fails, and the other end of the X.25 line is often normal, so if the normal end of the router has data transmitted to the abnormal end, the router considers the X.25 line to work normally. Therefore, there is no backup line at all.　　Steps for displaying backup Method Configuration　　1. Correctly configure trunk lines for normal

Introduction to the Catalyst5000 Series Cisco's ipvst5000 series Cisco LAN switches, in addition to the Catalyst 5000, also include four models: Catalyst 5002, Catalyst 5500, Catalyst 5505, and Catalyst 5509, all of which are Catalyst 5000 enhanced. The old device used in this project is a Catalyst 5509 switch. Taking the common Catalyst 5509 as an example,

A router is a commonly used network device. How should we configure VOIP implementation? What are the specific operation steps? The following article will give you a detailed introduction. Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco router configurati

Cisco switch iOS upgrade, actually quite simple, but need to note is, can not let the switch flash storage is empty, must have an iOS in, or no iOS in Flash, waiting to upload iOS with Xmodem, so your time can be a lot of waste ah.

CISCO mds FC optical fiber switch configuration reference(1) There are several concepts that must be clarified (different from brocade ):(1) brocade divides zones directly. While mds divides zones under vsan, mds can divide several vsan first, and each vsan includes several zones.(2) brocase: the default port is open, while the default port of mds is closed.(3) mds has a Default zone: "The Default Zone ". i
