show hardware internal statistics - fc1/13 There are no results applicable to port fc1/13. show hardware internal packet-dropped-reason - fc1/13
show hardware internal packet-flow dropped - fc1/13 This is in effect applying back-pressure to the sender so that it sends less packets into the MDS. Note: This indicates the MDS withheld B2B credits from the device connected to fc1/13 for at least 100ms. * Port Error Statistics for device Sabre-fcpĠxffffffff FCP_CNTR_RX_WT_AVG_B2B_ZERO 0x1c This command gives this example output: show hardware internal fc-mac port 13 error-statistics In effect, this is applying back-pressure to the sender so that it sends less packets into the MDS. Note that there is no indication of time in this counter.
This allows the receive B2B credits to transition to zero, which prevents the attached device from being able to send during the time it is at zero. Note: ' receive B2B credit transitions from zero' indicates the MDS withheld B2B credits from the device connected to fc1/13. Transmit B2B credit remaining- 128 - No change from previous value Receive B2B credit remaining - 32 - No change from previous value Receive B2B credit transitions from zero - +7408 Transmit B2B credit transitions from zero - 0 - No change from previous value These commands were issued: show interface fc1/13 Rtp-san-23-02-9148 fc1/13 - Port Connected to Sender Interface Counters - fc1/13
#Sabre emulator mac software
See Cisco Bug ID CSCts04123, "Slow drain support for atlantis/sabre." This bug was fixed in Cisco NX-OS Software Release 5.2(6) and later.
Cisco NX-OS Software Releases Earlier than 5.2(6) No Simple Network Management Protocol (SNMP) traps are sent, and the show system internal snmp credit-not-available command does not return anything. If you attempt to configure this counter, the error message "This counter is not supported on this platform" appears. The slow drain port-monitor policy does not contain tx-credit-not-available. See Cisco Bug ID CSCud93587, "MDS9148 OBFL doesn't contain FCP_CNTR_TX_WT_AVG_B2B_ZERO." This bug is not resolved yet. These counters are listed in the fc-mac counters, but do not show up in the onboard failure logging (OBFL) error-stats.
