Interface Configuration Guide
3HE 11011 AAAC TQZZA Edition: 01
The bandwidth indicated by the ETH-BN server includes the FCS; therefore, the include-fcs
option must be selected if the allow-eth-bn-rate-changes option is selected or the
dynamically changed bandwidth will not match the intended rate.
The hold-time is used to limit the number of bandwidth changes as requested by the ETH-BN
server. After a rate change occurs based on a Bandwidth Notification Message (BNM), any
BMN received before the hold timer expires will be ignored.
The no form of this command returns the value to the default.
Default no egress-rate
Parameters sub-rate — the egress rate in kb/s
Values 1 to 10000000
include-fcs — the egress rate limit is applied to the traffic rate egressing the port with
the 4-byte Ethernet FCS field included. This option must be selected if the allow-eth-
bn-rate-changes option is selected; otherwise, the dynamically changed bandwidth
will not match the intended rate.
allow-eth-bn-rate-changes — enables the Y.1731 ETH-BN client MEP option on the
port. The egress rate will be dynamically changed to the bandwidth indicated in
messages received from an ETH-BN server MEP. When enabled, the received rate
overrides the configured sub-rate for the port.
hold-time — configures the hold time for egress rate bandwidth changes based on a
received BNM, in seconds
Values 1 to 600
Default 5
encap-type
Syntax encap-type {dot1q | null | qinq}
no encap-type
Context config>port>ethernet
config>port>dsl
config>port>gpon
Description This command configures the encapsulation method used to distinguish customer traffic on
an Ethernet or DSL access port, network v-port, GPON port, or different VLANs on a network
port.
Before an MPR-e radio can be configured on an MWA port (see radio), the port must have
an encapsulation type of dot1q.
The qinq encapsulation type is not supported by a v-port, or by DSL or GPON modules on
the 7705 SAR-M. However, qinq encapsulation is supported by the DSL block on the
7705 SAR-Wx.
