G8264 Application Guide for ENOS 8.4
A routed port has the following characteristics:
 Does not participate in bridging.
 Does not belong to any user‐configurable VLAN.
 Does not implement any Layer 2 functionality, such as Spanning Tree Protocol
(STP).
Is always in a forwarding state.

 Can participate in IPv4 routing.
Can be configured with basic IP protocols, such as Internet Control Message

Protocol (ICMP), and with Layer 3 protocols, such as Protocol‐Independent
Multicast (PIM), Routing Information Protocol (RIP), Open Shortest Path First
(OSPF), and Border Gateway Protocol (BGP).
 Can be configured with Internet Group Management Protocol (IGMP) querier
and snooping functionality.
 Layer 3 configuration is saved even when the interface is shutdown.
 MAC address learning is always enabled.
 Tagging and port VLAN ID (PVID) tagging is disabled.
Flooding is disabled.

 Bridge Protocol Data Unit (BPDU)‐guard is disabled.
Link Aggregation Control Protocol (LACP) is disabled.

 Multicast threshold is disabled.
Static Multicast MAC and static unicast MAC can be configured.

Notes:
 Ports on which LACP or portchannel is enabled cannot be changed to routed
ports.
 Ports that have Static MAC addresses configured cannot be changed to routed
ports.
When a switch port is configured as a routed port, the following configuration
changes are automatically implemented:
 The port is removed from all the VLANs it belonged to.
 The port is added to an internal VLAN on which flooding is disabled. The ID of
this internal VLAN could be 4094 or lower. The internal VLAN is assigned to
Spanning Tree Group (STG) 1, if RSTP/PVRST is configured; or to Common
Internal Spanning Tree (CIST), if MSTP is configured. You cannot change the
VLAN number assigned to the routed port.
 STP is disabled and the port is set to a forwarding state.
Note: The maximum number of VLANs you can configure on the RackSwitch
G8264 is 4095. This maximum number will be reduced by the number of
routed ports you configure.
