cisco 3550 layer 3 switch

802.1p network services: Different Levels of gold, silver, and bronze services can be implemented based on different payment options, so as to ensure the services of high-priority users as much as possible. Supports the network layer-3 DiffServ service: it provides packet priority tag and priority differentiation processing. The above intelligent services can solve the problem of distribution efficiency an

The h3c layer-3 Switch acl is an example of a new library that can only access the electronic reading room, and cannot access other hosts on the Intranet, so as to avoid security impact. the IP address of the On-Internet www.2cto.com electronic reading room is not opened to 10.0.1.9, the new library plans to divide vlan 11, network segment 10.1.11.0/25, and vlan-

domain, or transmit the VTP broadcast information sent by other vswitches In The VTP domain, but it is not involved in the synchronization and allocation of The VTP domain, it does not pass its own VLAN configuration to other switches in The VTP domain. Its VLAN configuration only affects itself.The switch is in Server mode by default.4) create a VLAN. By default, the switch only has VLAN 1. You can use co

How to communicate with different vlan segments of a layer-3 switch can be achieved through the layer-3 function of the layer-3 Switch, that

Layer-3 egress connection to the internal port of the firewall It is recommended that layer-3 core switches use VLAN1 to connect to the firewall's internal port. The Intranet access to the Internet may be slow due to IP redirection !! The specific examples and solutions are as follows: The core of a certain Enterprise

eth1.200 hw ether 00: 05: 5D: 61: 00: 31, ifup eth1 A complete VLAN (interface) is successfully added. This function is equivalent to executing vlan 200, ip address 192.168.200.1 255.255.0 on a layer-3 switch. Configurations on L2 Switches The configuration on the L2 Switch is the same as before. Take AVAYA P334 as

Idea: Configure The VTP host and client, enable IP routing, and divide VLAN -----> define IP addresses for each VLAN port, and enable trunk ------> enable DHCP on The vtp server, and define IP-pool, set different CIDR blocks to VLAN interface IP addresses as gateways ------> Add ports to corresponding VLANs -------> set management IP addresses and passwords of vswitches 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/4C/42/wKiom1Q6Ms_AiVU2AAH5SP-f5do600.jpg "Title =" Capture 2.jp
