Chapter 1: Packet Forwarding Flashcards
Define a VLAN
vlan “vlan-id”
name “vlanname”
Configure an Interface as a trunkport
switchport mode trunk
Configure an interface as an access port assigned to a specific VLAN
switchport mode access
switchport access {vlan “vlan-id” | name “name”}
configure a static MAC address entry
mac address-table static mac-address vlan “vlan id” interface “interface id”
Clear MAC addresses from the MAC address table
clear mac address-table dynamic [{address “MAC address” | interface “interface id” | vlan “vlan id”}]
Assign an IPv4 address to an interface
ip address “ip address subnet mask”
Assping an IPV6 address to an interface
ipv6 address “ipv6 address/prefix length”
Modify the SDM database
sdm prefer {vlan | advanced}
Display interfaces that are configured as a trunk port and the vlans they permit
show interfaces trunk
Display the list of VLANs and their associated ports
