hold-time
Syntax hold-time [up hold-time-up | down hold-time-down]
no hold-time
Context config>port>ethernet
Description This command configures port link dampening timers, which reduce the number of link transitions
reported to upper layer protocols.
The hold-time value is used to dampen interface transitions.
When an interface transitions from an up state to a down state, it is immediately advertised to the rest
of the system, but subsequent interface down transitions are not advertised to upper layers until the
hold-time-down interval has expired. Likewise, when an interface transitions from a down state to an
up state, it is immediately advertised as up to the rest of the system, but subsequent up transitions are
not advertised until the hold-time-up interval has expired.
The no form of this command reverts to the default values.
Default down 0 or up 0— no port link dampening is enabled; link transitions are immediately reported to
upper layer protocols
Parameters down seconds — the interval, in tenths of seconds, used when an interface transitions from a down
state to an up state
Values 0 to 50
up seconds — the interval, in tenths of seconds, used when an interface transitions from an up state to
a down state
Values 0 to 50
mac
Syntax mac ieee-address
no mac
Context config>port>ethernet
Description This command assigns a specific MAC address to an Ethernet port. When the command is issued
while the port is operational, IP will issue an ARP, if appropriate, and BPDUs are sent with the new
MAC address.
The no form of this command returns the MAC address to the default value.
Default A default MAC address is assigned by the system
Parameters ieee-address — specifies the 48-bit MAC address in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff
where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are any non-broadcast,
non-multicast MAC, and non-IEEE reserved MAC addresses.
