Cisco switch port link type description: vlan description

Cisco switch port link type description: vlan description 1. an Access port can only belong to one VLAN and is generally used to connect to a computer. 2. A Trunk port can belong to multiple VLANs and can receive and send packets from multiple VLANs. It is generally used for ports connected between switches. 3. A Hybrid port can belong to multiple VLANs. It can receive and send packets from multiple VLANs. It can be used to connect switches or to users' computers. Configuration of Telnet logon mode when the Authentication mode is Scheme # telnet server enable # local-user guestservice-type telnetlevel 3 password simple 123456 # create and describe Vlan # system-view # Enter configuration options command Line [SwitchA] vlan 100 # create the current VLAN [SwitchA-vlan100] description Dept1 # description of the current VLAN [SwitchA-vlan100] port GigabitEthernet 1/0/1 # Add the current port to the same VLAN? Configure the port as the Trunk port, and allow VLAN10 and VLAN20 through [SwitchA] interface GigabitEthernet 1/1 # enter the current port [SwitchA-GigabitEthernet1/1] port link-type trunk # set the current port to relay [SwitchA-GigabitEthernet1/1] port trunk permit vlan all # Allow all VLANs through [SwitchA-vlan100] quit # exit DHCP typical configuration example: # [SwitchA] dhcp server ip-pool 0 # create DHCP group [SwitchA-dhcp-pool-0] network 10.1.1.0 mask 255.255.0 # address pool range [SwitchA-dhcp-pool-0] domain-name aabbcc.com # WINS server location Address [SwitchA-dhcp-pool-0] dns-list 10.1.1.2 # DNS server address [SwitchA-dhcp-pool-0] nbns-list 10.1.1.4 # From DNS preparation [SwitchA] dhcp server forbidden-ip 10.1.1.2 # Not involved Address Allocation address (Reserved address) [SwitchA] dhcp server detect # configure the pseudo server detection function.

Link aggregation allows inbound/outbound loads to be shared among the member ports in the aggregation Group to increase bandwidth. In addition, member ports in the same aggregation group are dynamically backed up to improve connection reliability. # Create L2 aggregation Port 1.

System-view [SwitchA] ip route-static 0.0.0.0 0.0.0.0 1.1.4.2 # configure the default route # configure two static routes on Switch B.
