Interface names
Eth interfaces (Non-LAG related interfaces) share the same name as the E7 Ethernet
Ports (card 1/Eth port g1, for example 1/g1)
g(port number) = GE(port number)
x(port number) = 10GE(port number)
LAG interfaces are named at the time of creation
Interface roles
Each GE and 10GE interface in the E7 has one of the following configuration-role types:
Trunk:
A port connecting to other equipment belonging to the service provider or to
another service domain with consistent VLAN tagging levels. These ports may also be
referred to as Network ports or Provider ports in industry standards. These ports support
outer VLAN tag plus MAC switching.
Examples of trunk ports are 10G ERPS transport ports and GE uplinks. Trunk ports can be
configured for link aggregation, RSTP, or ERPS. To properly process ingress double tags, the
GE network interface (uplink) must be configured as a Trunk role.
Edge:
A port facing customer equipment or facing reduced functionality devices, alternative
administrative domains, or managed CPE. Generally, this E7 Ethernet port interface is where
all classification is first performed on ingress traffic (if customer facing). The E7 Ethernet
interface is also expected to add, replace, or remove one or more VLAN tags on edge traffic.
RSTP and LAG networking protocols are supported.
Examples of an edge port would include GE ports to managed CPE, a GE/10GE port to
external equipment which may use different tagging levels, or GPON ports.
Access:
A port facing untrusted customer equipment or other devices serving subscribers.
Generally, this port interface is where individual subscriber services are defined and enforced
(bandwidth limits, security, multicast profiles). Networking protocols are not supported.
Examples of an access port would be point-to-point connections to subscribers or other
devices serving subscribers.
VLAN support
By default, every E7 Ethernet port with a trunk or edge interface on the unit is a member of
VLAN 1, the Native VLAN. The Native VLAN is available to pass any untagged traffic. You
can provision an E7 Ethernet port interface to use a different existing VLAN as the Native
VLAN.
To forward untagged traffic on E7 Ethernet ports with an access interface, an add-tag action
must be applied to untagged frames, assigning the traffic to a designated VLAN.
Tagged traffic that does not match any of the tagging criteria is dropped.
