Basic Ethernet Features - Zte ZXR10 5900E Product Description

LACP (Link Aggregation Control Protocol) follows IEEE 802.3ad standard. LACP
aggregates multiple physical ports dynamically to Trunk group via protocol to form a
logical port. LACP generates aggregation to get maximum bandwidth.
When configure link aggregation service on ZXR10 5900E, the following principles
should be followed:

Totally 32 Trunk groups should be configured. Each Trunk group consist of 8
member port at most.

Support cross-interface board aggregation. Member port can be distributed on any
interface board. But the selected port must be working in full-duplex modem and the
working speed must be the same.

The member port mode can be access, trunk or hybrid. But they must keep the
same.
The logical port formed by link aggregation on ZXR10 5900E is called smartgroup which
can be used as common port.

Basic Ethernet Features

ZXR10 5900E series supports the following basic Ethernet features:

Port mirroring

Port mirroring service can replicate the data of one or more than more ports
(reflector port)on the switch to a designated destination port (monitoring port). The
monitoring port can get the data on these reflector ports via mirroring image, so that,
it can carry out network traffic analysis and failure diagnosis. Also, it supports
remote SPAN（RSPAN、ERSPAN）.

Broadcasting storm suppression
It can restrict the number of broadcasting message allowed to pass Ethernet port per
second. When the broadcasting traffic exceeds the value user set, the system discards
the broadcasting traffic to control it to a reasonable scale. In this way, it effectively
suppresses broadcasting storm, avoids network congestion and ensures normal service
