Description
Control-timeout
Timeout period used for timing out most
request/response control frame interactions.
request/response control frame interactions.
VCC-timeout-period
An LEC should release any Data Direct VCC that has
not been used to transmit or receive any data frames
for the length of the VCC-timeout-period.

for the length of the VCC-timeout-period.
Aging-time
The maximum time that an LEC will maintain an entry
in its LE_ARP cache in the absence of a verification of
that relationship.
in its LE_ARP cache in the absence of a verification of
that relationship.
Forward-delay-time
The maximum time that an LEC will maintain an entry
for a non-local MAC address in its LE_ARP cache in the
absence of a verification of that relationship, as long as
the topology-change-flag is true.

The maximum time that the LEC expects an LE_ARP
request/response cycle to take. Used for retries and
verifies.
request/response cycle to take. Used for retries and

Topology-change-flag
Boolean indication that the LEC is using the
forward-delay-time instead of aging-time to age
non-local entries in its LE_ARP cache.

non-local entries in its LE_ARP cache.
Flush-timeout
Time limit to wait to receive an LE_FLUSH response
after the request has been sent, before taking recovery
action.
after the request has been sent, before taking recovery
action.
Path-switching-delay
The time since sending a frame to the BUS after which
the LEC may assume that the frame has been either
discarded or delivered to the recipient.
