Interface Configuration of layer-3 Switch Load Balancing

Layer-3 Switch SLB interface configuration layer-3 Switch configuration-configure a group of layer-2 ports www.2cto.com configure terminal to enter the configuration status nterface range {port-range} to enter the group configuration status layer-3 Switch configuration-configure Layer-3 Ports configure terminal enters the configuration Status interface {fastethernet | gigabitethernet} interface-id} | {vlan-id} |
{Port-channel-number}: enter the port configuration status. no switchport changes the physical port to a layer-3 port ip address ip_address subnet_mask. Configure the ip address and mask no shutdown. Example: Switch (config) # interface gigabitethernet0/2 Switch (config-if) # no switchport Switch (config-if) # ip address 192.20.135.21 255.255.255.0 Switch (config-if) # no shutdown layer-3 Switch configuration-configure VLAN configure terminal to enter the configuration status vlan VLAN-id enter a vlan number and then enter the VLAN configuration status, you can enter a new VLAN number or the old one to modify the na. (Me vlan-name is optional) enter a VLAN name. If no VLAN name is configured, the default name is the four-digit number filled with 0 before the VLAN number, for example, VLAN0004 is the default name mtu-size (optional) of VLAN4. For example, Switch # configure terminal Switch (config) # vlan 20 Switch (config-vlan) # name test20 Switch (config-vlan) # end or Switch # vlan database Switch (vlan) # vlan 20 name test20 Switch (vlan) # exit layer-3 Switch configuration -- port assigned to a VLAN configure terminal enters the configuration Status interface-id enters the port to be allocated switchport mode access Definition L2 switchport access vlan-id: assign a port to a VLAN. For example, Switch # configure terminal Enter configuration commands, one per line. end with CNTL/Z. switch (config) # interface fastethernet0/1 Switch (config-if) # switchport mode access Switch (config-if) # switchport access vlan 2 Switch (config-if) # end Switch # configure VLAN trunk configure terminal to enter configuration Status interface-Id to enter port configuration status switchport trunk encapsulation {Isl | dot1q | negotiate}: configure the trunk to encapsulate ISL, 802.1Q, or L3 switch configurations. For example, switchport mode {dynamic {auto | desirable} | trunk}: configure the L2 trunk mode. Dynamic auto-automatically negotiate whether it is a trunk dynamic desirable-set the port to trunk. If the peer port is a trunk or desirable, configure Native VLAN (802.1q) or automatic mode, trunk-set the port to a forced trunk mode, regardless of whether the peer port is a trunkswitchport access vlan-id (optional) specify a default vlan, if the port is no longer trunkswitchport trunk native vlan-id specifies 802.1Q native VLAN Number Switch # configure terminal Enter configuration commands, one per line. end with CNTL/Z. switch (config) # interface fastethernet0/4 Swit Ch (config-if) # switchport mode trunk Switch (config-if) # switchport trunk encapsulation dot1q Switch (config-if) # end layer-3 Switch configuration-define the VLAN configure terminal Sub-ports allowed by TRUNK to enter the configuration Status interface-id to enter the port configuration switchport mode trunk to configure the L2 port to trunk switchport trunk allowed vlan {add | all | subnet T | remove} vlan-list (optional) configure the VLAN allowed by the trunk. use add, all, listen t, remove no switchport trunk allowed vlan to allow all VLAN passing examples: www. 2cto.com Switch (config) # interface fastethernet0/1 Switch (config-if) # switchport trunk allowed vlan remove 2 Switch (config-if) # end layer-3 Switch configuration-configure Native VLAN (802.1q) configure terminal enters the configuration Status interface-id enters the port configured as 802.1qtrunk switchport trunk native vlan-Id configure native vlan no switchport trunk native VLAN port configuration command back to the default status layer-3 Switch configuration -- configure the port weight-based Server Load balancer configure terminal to Switch 1 configuration status vtp domain do Main-name: Configure VTP domain vtp mode server to configure Switch 1 to VTP server. show vtp status verify VTP configuration show vlan verify VLAN configure terminal enter configuration status interface fastethernet 0/1 enter F0/1 port switchport trunk encapsulation {isl | dot1q | negotiate} configure trunk encapsulation switchport mode trunk configure to trunk show interfaces fastethernet0/1 switchport to verify VLAN configuration configure the interface for Server Load balancer in the preceding steps on another switch.
