sifExpectSqe {sifEntry 43}
Boolean Read-Write
Whether the port should expect SQE, also known as “heartbeat” (not applicable
for ports other than CSMA/CD ports).
sifFilterLocal {sifEntry 44}
Boolean Read-Write
Whether the port should attempt to filter local traffic, bypassing all statistics
accumulation, rather than passing the local traffic to the Packet Processing
Engine. Filtering local traffic is not available for UART and WAN ports.
sifInQLen {sifEntry 45}
Gauge Read-Write
The maximum length ever obtained by the port’s inbound packet queue (in
packets). The size of a port’s inbound packet queue is periodically polled (rather
than recalculated whenever a packet is added), so sifInQLen is an approximation
of the maximum length.
sifFrameSwitching {sifEntry 46}
Integer Read-Write
Valid for Token Ring ports. Options include:
• enabled (1)
• disabled (2)
Default is disabled (2). If enabled, frames may be bridged between token ring
ports on the same board at higher throughput and lower latency than is otherwise
possible. Address statistics will not reflect any frames forwarded in this manner.
This applies only to transparent bridging, and must be enabled on both the entry
and the exit port.
sifRingDrops {sifEntry 47}
Counter Read-Only
Only valid for 802.5 Token Ring, Number of times the ring left the open state.
sifAdapterChecks {sifEntry 48}
Counter Read-Only
Only valid for 802.5 Token Ring, Number of times the MAC chip experienced an
internal hardware failure and had to be reset.
