Chapter 2 Catalyst 3560 Switch Cisco IOS Commands switchport access These restrictions apply to dynamic-access ports: • The software implements the VLAN Query Protocol (VQP) client, which can query a VMPS such as a Catalyst 6000 series switch. The Catalyst 3560 switches are not VMPS servers. The VMPS server must be configured before a port is configured as dynamic. • Use dynamic-access ports only to connect end stations. Connecting them to switches or routers (that use bridging protocols) can cause a loss of connectivity. • Configure the network so that STP does not put the dynamic-access port into an STP blocking state. The Port Fast feature is automatically enabled on dynamic-access ports. • Dynamic-access ports can only be in one VLAN and do not use VLAN tagging. • Dynamic-access ports cannot be configured as - Members of an EtherChannel port group (dynamic-access ports cannot be grouped with any other port, including other dynamic ports). - Source or destination ports in a static address entry. - Monitor ports. Examples This example shows how to change a switched port interface that is operating in access mode to operate in VLAN 2 instead of the default VLAN: Switch(config-if)# switchport access vlan 2 You can verify your setting by entering the show interfaces interface-id switchport privileged EXEC command and examining information in the Administrative Mode and Operational Mode rows.
