VLAN 60, VLAN 70, VLAN 80, and VLAN 90. Catalyst 3550-24-EMI is divided into four VLANs: VLAN 10, VLAN 20, VLAN 30, and VLAN 40. The Catalyst 3550-24-SMI is divided into two VLANs: VLAN 60 and VLAN 80. The two Catalyst 2950G-24-SMI switches are located in the same VLAN. * ************************** Instance analysis *********** ***************** Because all

analysis Since all Catalyst 2950G switches are a stand-alone VLAN, you must first create a VLAN (VLAN 60~vlan 90) on these switches and assign all ports to that VLAN. Then, create the VLAN separately on the corresponding port on the Catalyst 4006 switch. The 1000base-x port of Catalyst 4006 is connected to the 1000base-x port of each

Speed-limiting switches are typically on three or more switches, and the new switch model two-tier device since 2008 can achieve the QoS speed limit of 1Mbps, such as the Cisco 2960 series switches. After this, most of the domestic standard two-layer switches can be long speed limit, the accuracy of the basic can reach 1Mbps, such as ZTE's standard two layer, H3C standard two layer can do. Older Cisco standard two-layer switches such as 2950-class swi

The naming rules for Cisco switches are more complex than the naming rules for routing,Look at these:ws-c2960-24tc-l, WS-C2950G-24-EI-DC, Ws-c2960-24tt-l, Ws-c3750g-24ts-e, Ws-c3750g-24t-s, We didn't find them on the switch, we just saw the Catalyst 2950 series and wrote it all: The Cisco Catalyst 2950 Series, which me

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. Because the Rommon mode is not available for the Cisco Catalyst 2950, 2960, 3550 Switch lost iOS or iOS failure, because there is no, only the Cisco

Software and Hardware running on Cisco Catalyst 2950, Catalyst 3550, and Catalyst 4000 series switches can also implement appropriate traffic classification and isolation on all ports. VLAN attack 2.

The management IP address is 10.196.197.149, the port number is FastEthernet0/8, and is in vlan1. This means that the PC Connected to NetTool is located in VLAN1.
