Purpose
• For interface-id, specify the destination port. The destination
interface must be a physical port; it cannot be an EtherChannel,
and it cannot be a VLAN.
• (Optional) [, | -]—Specifies a series or range of interfaces. Enter
a space before and after the comma or hyphen.
• (Optional) encapsulation replicate specifies that the destination
interface replicates the source interface encapsulation method.
If not selected, the default is to send packets in native form
(untagged).
• ingress enables forwarding of incoming traffic on the destination
port and to specify the encapsulation type:
◦dot1q vlan vlan-id—Accepts incoming packets with IEEE
802.1Q encapsulation with the specified VLAN as the
default VLAN.
◦untagged vlan vlan-id or vlan vlan-id—Accepts incoming
packets with untagged encapsulation type with the
specified VLAN as the default VLAN.
