Parameter
ratio:
Maximum ratio of the received broadcast traffic to the total bandwidth on an
Ethernet port. The value ranges from 1 to 100 and defaults to 100. The smaller
the ratio is, the less broadcast traffic is allowed.
bandwidth
bandwidth: Specifies the maximum bandwidth of
broadcast traffic received on the Ethernet port. For a 100 Mbps port, the bandwidth
argument is in the range of 1 to 100 (in Mbps); for a gigabit port, the
bandwidth argument is in the range of 1 to 1000 (in Mbps).
pps pps: Specifies the maximum number of broadcast packets allowed to be
received per second on an Ethernet port (in pps).
l
For a 100 Mbps Ethernet port, the pps
argument is in the range of 0 to 148,810.
l
For a gigabit Ethernet port, the pps
argument is in the range of 0 to 1,488,100.
Description
Use the broadcast-suppression
command to limit broadcast traffic allowed to be received on the current port.
Use the undo broadcast-suppression
command to restore the default broadcast suppression setting.
When incoming broadcast traffic exceeds the
broadcast traffic threshold you set, the system drops the packets exceeding the
threshold to reduce the broadcast traffic ratio to the reasonable range, so as
to keep normal network service.
By default, broadcast suppression is
disabled.
l
Broadcast suppression is set in different ways
for different LPUs of the S7500 series switches: For type-A LPUs, broadcast
suppression must be set in VLAN view; for non-type-A LPUs, broadcast
suppression must be set in Ethernet port view.
l
Type-A LPUs include LS81FT48A, LS81FM24A, LS81FS24A,
LS81GB8UA, and LS81GT8UA.
A port supports one way of broadcast
suppression at the same time. If broadcast suppression has been configured for
a port for multiple times, only the latest configuration takes effect.

# Allow incoming broadcast traffic to
occupy at most 20% of the bandwidth on the port.

Parameter
ratio:
Maximum ratio of received multicast traffic to the total bandwidth on the
Ethernet port. The value ranges from 1 to 100 (in step of 1) and defaults to
100. The smaller the ratio is, the less multicast traffic is allowed to be
received.
mbps-value:
Maximum bandwidth (in Mbps) for receiving multicast traffic on an Ethernet
port. The range of the mbps-value argument depends on the port type:
l
1 to 100 for 100 Mbps Ethernet ports;
l
1 to 1,000 for Gigabit Ethernet ports;
l
1 to 10,000 for 10 Gbps Ethernet ports.
kbps
kbps-value: Specifies the maximum bandwidth (in
Kbps) for receiving multicast traffic, in the range of 64 to 1,024,000 in the
steps of 64.
max-pps:
Maximum number of multicast packets allowed to be received per second on the

port type.
l
1 to 148,810 for 100 Mbps Ethernet ports;
l
1 to 1,488,100 for Gigabit Ethernet ports;
l
1 to 262,143 for 10 Gbps Ethernet ports.
Description
Use the multicast-suppression
command to limit multicast traffic allowed to be received on the current port.
Use the undo multicast-suppression
command to restore the default multicast suppression setting on the current
port.
When incoming multicast traffic on the port
exceeds the multicast traffic threshold you set, the system drops the packets
exceeding the threshold to reduce the multicast traffic ratio to the reasonable
range, so as to keep normal network service.
By default, the switch does not suppress
multicast traffic.
Caution:
Note that type-A LPUs (including LS81FT48A, LS81FM24A, LS81FS24A,
LS81GB8UA, and LS81GT8UA) do not support multicast suppression.

Parameter
vlan-id:
VLAN ID defined in IEEE802.1Q, in the range of 1 to 4094. It is 1 by default.
Description
Use the port hybrid pvid vlan
command to set the default VLAN ID for the hybrid port.
Use the undo port hybrid pvid
command to restore the default VLAN ID of the hybrid port.
Set the default VLAN ID of the local hybrid
port to the same value as that of the hybrid port on the peer switch.
Otherwise, packets cannot be forwarded properly.
Related command: port link-type.
Example
# Set the default VLAN ID of the hybrid
port Ethernet1/0/1 to 100.

Parameter
vlan-id-list:
VLAN range to which the hybrid port will be added. The VLAN range can be
discrete. vlan-id-list = [ vlan-id1 [ to vlan-id2 ]
]&<1-10>, where, vlan-id is in the range of 1 to 4094, and
&<1-10> means you can input up to ten VLAN IDs/ID ranges.
tagged:
Keeps VLAN tags when the packets of the specified VLANs are forwarded.
untagged:
Strips VLAN tags when the packets of the specified VLANs are forwarded.
Description
Use the port hybrid vlan command to
add the hybrid port into specified VLANs.
Use the undo port hybrid vlan
command to remove the hybrid port from specified VLANs.
A hybrid port can belong to multiple VLANs.
When you use the command several times, all VLAN specified by the command will
be allowed to pass the port.
The VLAN specified by the vlan-id
argument must exist. Otherwise, this command is invalid.
Related command: port link-type.
Example
# Add the hybrid port Ethernet1/0/1 to VLAN
2, VLAN 4 and VLAN 50 through VLAN 100, and keep the VLAN tags when the packets
of these VLANs are sent through the port.

Parameter
access: Sets
the port as an access port.
hybrid: Sets
the port as a hybrid port.
trunk: Sets
the port as a trunk port.
Description
Use the port link-type command to
set the link type of the current Ethernet port.
Use the undo port link-type command
to restore the default link type.
By default, the link type of a port is
access.
The three types of ports can co-exist on
the same Ethernet switch. However, a trunk port cannot be directly switched to
a hybrid port, and vice versa. To set a trunk/hybrid port to hybrid/truck, you
must first set the port to an access port and then set the access port to the
required type. For example, a trunk port cannot be directly set to a hybrid
port. You must set the trunk port to an access port and then set it to a hybrid
port.
Example
# Specify Ethernet1/0/1 as a trunk port.

all: Adds
the trunk port into all VLANs.
Description
Use the port trunk permit vlan

Use the undo port trunk permit vlan

Parameter
vlan-id:
VLAN ID defined in IEEE802.1Q, in the range of 1 to 4094. It is 1 by default.
Description
Use the port
trunk pvid vlan command to set the default VLAN ID
for the trunk port.
Use the undo port trunk pvid command to restore the
default setting.
To guarantee the proper packet
transmission, the default VLAN ID of the local trunk port must be identical
with that of the trunk port on the peer switch.
