Field
Description
Hardware
Hardware type.
Hardware is Token Ring
indicates that the
board is a CSC-R board.
Hardware is 16/4 Token Ring
indicates that the board is a CSC-R16 board. Also shows
the address of the interface.
Internet address
Lists the Internet address followed by subnet mask.
MTU
Maximum transmission unit of the interface.
BW
Bandwidth of the interface in kilobits per second.
DLY
Delay of the interface in microseconds.
rely
Reliability of the interface as a fraction of 255 (255/255 is
100 percent reliability), calculated as an exponential
average over five minutes.
load
Load on the interface as a fraction of 255 (255/255 is
completely saturated), calculated as an exponential average
over five minutes.
Encapsulation
Encapsulation method assigned to interface.
loopback
Indicates whether loopback is set.
keepalive
Indicates whether keepalives are set.
ARP type:
Type of Address Resolution Protocol assigned.
Ring speed:
Speed of Token Ring— 4 or 16 Mbps.
{
Single ring
|
multiring
node
}
Indicates whether a node is enabled to collect and use
source routing information (RIF) for routable Token Ring
protocols.
Group Address:
Interface's group address, if any. The group address is a
multicast address; any number of interfaces on the ring
may share the same group address. Each interface may
have at most one group address.
Last input
Number of hours, minutes, and seconds since the last
packet was successfully received by an interface. Useful
for knowing when a dead interface failed.
Last output
Number of hours, minutes, and seconds since the last
packet was successfully transmitted by an interface.
output hang
Number of hours, minutes, and seconds (or never) since the
interface was last reset because of a transmission that took
too long. When the number of hours in any of the “last”
fields exceeds 24 hours, the number of days and hours is
printed. If that field overflows, asterisks are printed.
