[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for layer-3 switches so that VLAN10 and VLAN20 members can obtain IP a

Calculate the bandwidth of the backboard of a Cisco switch. It is the maximum amount of data that can be transferred between the vswitch interface processor, interface card, and data bus. The higher the bandwidth of the backboard of A vswitch, the stronger the ability to process data, but the design cost will also rise. Www.2cto.com but how can we check whether the bandwidth of A vswitch is sufficient? Obvi

I am eager for the first time to switch between vlan routing and nat addresses of Cisco switches. I am very energetic and have an undefeated spirit. I am ready to continue to answer questions during multiple rounds of interviews. My little brother squashed his eyes and took out the bottom of the press box: If my company has two Internet interfaces, A and B, respectively. The following vswitch divides multip

Cisco switches enable port speed limiting As shown in, Node switch 3550 is placed in an office room. The networks of all office companies are from this place. How does the operator configure network bandwidth settings for each company on this device? Let's take the IT Training Center of XX foreign companies as an example. The IT Training Center of XX foreign companies applied for a 2 m link. Step-1 Rongxi

Disable forwarding of a specific MAC address on a cisco SwitchIt is really annoying to see other illegal DHCP in the LAN. In addition to the dhcp snooping method, you can also directly disable the mac address! The MAC address of machine A is 00-01-02-03-04-05, which is connected to port F0/3 of Switch B, port F0/3 is in VLAN3. Currently, forwarding of A is blocked on port B. You can set the following accord

Cisco switch port broadcast storm settings are more practical. When a port receives a large number of broadcast, unicast, Or multicast packets, a broadcast storm occurs. Forwarding these packets will slow down the network or cause timeout. Using broadcast storm control on ports can effectively avoid network paralysis caused by hardware damage or link failure. By default, broadcast, multicast, and unicast st
