storm-control broadcast
This command enables broadcast storm recovery mode. If the mode is enabled, broadcast storm
recovery with high and low thresholds is implemented.
The threshold implementation follows a percentage pattern. If the broadcast traffic on any Ethernet
port exceeds the high threshold percentage (as represented in
Table 1
) of the link speed, the switch
discards the broadcasts traffic until the broadcast traffic returns to the low threshold percentage or
less. The full implementation is depicted in the
Table 1
.

no storm-control broadcast
This command disables broadcast storm recovery mode.
The threshold implementation follows a percentage pattern. If the broadcast traffic on any Ethernet
port exceeds the high threshold percentage (as represented in
Table 2
) of the link speed, the switch
discards the broadcasts traffic until the broadcast traffic returns to the low threshold percentage or
less. The full implementation is depicted in the
Table 2
.

show mac-address-table multicast
This command displays the Multicast Forwarding Database (MFDB) information. If the command
is entered with no parameter, the entire table is displayed. This is the same as entering the optional
all
parameter. The user can display the table entry for one MAC Address by specifying the MAC
address as an optional parameter.
Format
show mac-address-table multicast
<macaddr | all>
Mode
Privileged EXEC
Mac Address
A multicast MAC address for which the switch has forwarding and or filtering
information. The format is two-digit hexadecimal numbers that are separated by
colons, for example 01:23:45:67:89:AB. In an IVL system the MAC address
will be displayed as a MAC address and VLAN ID combination of 8 bytes.

Type
This displays the type of the entry. Static entries are those that are configured by
the end user. Dynamic entries are added to the table as a result of a learning pro-
cess or protocol.
Component
The component that is responsible for this entry in the Multicast Forwarding
Database. Possible values are IGMP Snooping, GMRP, and Static Filtering.
Description
The text description of this multicast table entry.
Interfaces
The list of interfaces that are designated for forwarding (Fwd:) and filtering
(Flt:).
Forwarding Interfaces
The resultant forwarding list is derived from combining all the component’s for-
warding interfaces and removing the interfaces that are listed as the static filter-
ing interfaces.
show mac-address-table static
This command displays the Static MAC Filtering information for all Static MAC Filters. If <all> is
selected, all the Static MAC Filters in the system are displayed. If a macaddr is entered, a vlan
must also be entered and the Static MAC Filter information will be displayed only for that MAC
address and VLAN.
Format
show mac-address-table static
{<macaddr> <vlanid> |
all}
Mode
Privileged EXEC
MAC Address
Is the MAC Address of the static MAC filter entry.
VLAN ID
Is the VLAN ID of the static MAC filter entry.
Source Port(s)
Indicates the source port filter set's slot and port(s).
Destination Port(s)
Indicates the destination port filter set's slot and port(s).
show mac-address-table staticfiltering
This command displays the Static Filtering entries in the Multicast Forwarding Database (MFDB)
table.
Format
show mac-address-table staticfiltering
Mode
Privileged EXEC
Mac Address
A unicast MAC address for which the switch has forwarding and or filtering
information. The format is 6 or 8 two-digit hexadecimal numbers that are sepa-
rated by colons, for example 01:23:45:67:89:AB. In an IVL system the MAC
address will be displayed as 8 bytes.

is the
slot/port configured as the probe port. If this value has not
been configured, 'Not Configured' will be displayed.
Monitored Port slot/port
is the
slot/port configured as the monitored port.
If this value
has not been configured, 'Not Configured' will be displayed.

Slot/Port
Valid slot and port number separated by forward slashes.
Type
If not blank, this field indicates that this port is a special type of
port. The possible values are:
Mon
- this port is a monitoring port. Look at the Port Monitoring
screens to find out more information.
Lag
- this port is a member of a port-channel (LAG).
Probe
- this port is a probe port.
Admin Mode
Selects the Port control administration state. The port must be
enabled in order for it to be allowed into the network. - May be
enabled or disabled. The factory default is enabled.
Physical Mode
Selects the desired port speed and duplex mode. If auto-negotia-
tion support is selected, then the duplex mode and speed will be
set from the auto-negotiation process. Note that the port's maxi-
mum capability (full duplex -100M) will be advertised. Other-
wise, this object will determine the port's duplex mode and
transmission rate. The factory default is Auto.
Physical Status
Indicates the port speed and duplex mode.
Link Status
Indicates whether the Link is up or down.
Link Trap
This object determines whether or not to send a trap when link
status changes. The factory default is enabled.
