3.3 Port mirroring
Function Brief
Port mirroring is also called port monitoring. Port monitoring is a data
packet acquisition technology. It can be configured on a switch to copy data
packets from one or more ports (mirror source ports) to a specified port
(mirror destination port). The destination port is connected to a host installed
with the packet analysis software. The software analyzes the collected
packets to implement network monitoring and eliminating network faults.

3.4 Link aggregation
Static aggregation configuration commands include:
Trunk
Dynamic aggregation configuration commands include:
lacp enable | disable
lacp active | passive
lacp key
lacp port-priority
Function Brief
Link aggregation is used to form a logical port using multiple physical
ports of a switch. Multiple links within the same aggregation group are
deemed as a larger bandwidth logical link.
By link aggregation, the communication traffic is shared among
member ports of the aggregation group, and thus the bandwidth is increased.
Besides, member ports of the same aggregation share dynamic backups
with each other, and thus the link reliability is improved.
3.4.1 trunk
Member ports of the same aggregation group shall have the same
configurations. The configurations mainly include STP, QoS, VLAN, port
attribute, MAC address learning, ERPS configuration, loop protection
configuration, mirror, 802.1x, IP filtering, MAC filtering, port isolation, etc.
Command Description
both-mac
Based on the source mesh MAC load balancing
dst-mac
Based on the destination MAC load balancing
src-mac
Based on the source MAC load balancing
interface trunk [trunk ID]

switch(config)# interface trunk 1
switch(config)# interface G1
switch(config-G1)# trunk 1

//It specifies the role of a port, which is active or passive.
Parameter
None
Default
active
Command Mode
Interface configuration mode
Example
switch(config)#interface G1
switch(config-G1)# lacp active
3.4.5 lacp key
Command Description
LACP key refers to the management key value of a dynamic
aggregation port and determines whether the port can be added into
an aggregation port. LACP protocol generates an operation key
based on the port configuration (that is, the rate, duplex, basic
configuration and management key). Members of a dynamic
aggregation group can only be aggregated when they have the
same operation key.
Parameter
<1-65535>: The key value is manually specified. The value ranges
from 1 to 65535.
auto: The key value is automatically negotiated.
Default
auto
Command Mode
Interface configuration mode
Example
switch(config)# interface G1
switch(config-G1)# lacp key 100
3.4.6 lacp port-priority
Command Description
lacp port-priority <1-32768>
//This command is used to configure the priority of an LACP port.
Parameter
<1-32768>: It specifies the priority range. A smaller value indicates a
higher priority.
Default
0
Command Mode
Interface configuration mode
Example
switch(config)# interface G1
switch(config-G1)# lacp port-priority 100
3.4.7 example
The link aggregation is used to increase the bandwidth of device-level serial
ports and share loads based on the source/destination MAC address.
SW1/SW2:
switch# configure terminal
switch(config)# load-balance both-mac
switch(config)# interface trunk 1
switch(config)# interface G1
switch(config-G1)# trunk 1
switch(config)# interface trunk 1
switch(config)# interface G2
switch(config-G1)# trunk 1
phenomenon:
After aggregation, two links form one logical link and thus the
bandwidth is doubled. Besides, the load is shared based on the source or
destination MAC address. When one link in the aggregation group is
disconnected, the packet is sent through another link, and thus the
communication is not interrupted.
4. Advanced configuration commands
4.1 VLAN config
VLAN configuration commands include:
switchport mode
switchport pvid
switchport trunk|hybrid| access
show vlan
Function Brief
Ethernet is a shared communication media based on the Carrier
Sense Multiple Access/Collision Detect (CSMA/CD) technology. A LAN built
using the Ethernet technology is not only a collision domain, but also a
broadcast domain. When the number of hosts on the network is large, the
collision becomes serious, broadcast flooding occurs, and the performance
is significantly degraded. Even worse, the network is unavailable.
Deployment of bridges or L2 switches on the Ethernet can resolve the
problem of serous collision, but still cannot isolate broadcast packets. To
address this issue, the Virtual Local Area Network (VLAN) technology
emerges. This technology can divide a physical LAN into multiple logical
LANs, that is, VLANs. Hosts located in the same VLAN can directly
communicate with each other, but hosts located in different VLANs cannot
communicate with each other. In this way, broadcast packets are confined in
the same VLAN. That is, each VLAN is a broadcast domain.
Advantages of VLAN are as follows:
1) Improve network performance. Broadcast packets are confined in the
VLAN, which effectively controls broadcast storms of the network, saves the
network bandwidth, and improves the network processing capability.
2) Enhance network security. Devices in different VLANs cannot access
each other, and hosts in different VLANs cannot directly communicate with
each other. Packets must be forwarded at L3 through network layer devices,
such as routers or L3 switches.
3) Simplify network management. Hosts in the same virtual work group are
not limited to a certain physical range, which simplifies network management,
and makes it convenient for people in different areas to set up work groups.

Access mode
Command Mode
Interface configuration mode
A switch port supports the following modes:
Access mode: The port belongs to only one VLAN, and only
sends and receives untagged Ethernet frames.
Trunk mode: The port is connected with other switches, and can
receive and send tagged Ethernet frames.
Hybrid mode: The port can be connected to a PC or a switch and
router. (The hybrid mode is the combination of the access mode
and the trunk mode.)
Example
//The port is configured to VLAN trunk /hybrid/access.
Switch(config)# interface T1
Switch(config-T1)#switchport mode trunk /hybrid/access
