CRC errors are in the COUNTER attribute partition for the LINE subentity.
e.g. MCC> SHOW TRANSLAN .FOO LINE * ALL COUNT

FCS :== Frame Check Sequence

MCC> RESET TRANSLAN .FOO DEFAULTS = TRUE
will reboot the Translan (and consequently reset the counters...)

Well, I'm curious too, Rick. You say it shows up in FCL but NOT the Iconic
Map????
- What version of software are you running on the TransLANs?
- What variant of TransLANs are you using? III, 350, 320, 335?
- Can you post a snapshot of the SHOW Commands you used?
- Can you post the output of a SHOW LINE * ALL CHAR, too?
The only thing I can think of offhand is if we may be seeing some weird
behavior about handling of the LINE variants...
CRC Errors is a Counter Attribute for the LINE subentity, but ONLY for
LINEs that return "Link Type = Vitalink Serial". (i.e. there's a DEPENDS
ON clause in the MSL).
If the "Link Type" attribute of the lines you're looking at are NOT
"Vitalink Serial" (i.e. you're looking at Ethernet Ports) then you will NOT
see the CRC Errors Counter returned.

3272.4 | More on Counters - I'm confused! | ODIXIE::PEACOCKR | | Tue Jun 30 1992 18:15 | 73 |
| I just dialed in to a customer site to try it from the command line.
This is a Vitalink Translan 350. I tried the command on both line 1
and line 2 (which, as far as I know are being used). Here's what I
got:
MCC> show translan atlanta_dome line 1 all counters
TRANSLAN DSP_NS:.atlanta_dome LINE 1
AT 30-JUN-1992 17:06:40 Counters
Examination of attributes shows:

Why are the counters so different? I have several on Line 2, including
the CRC errors, which didn't show up on line 1. Is there something
different in the configuraton of the lines that would make them so
different?
Thanks,
Rick

| I think I may have figured out my mistake.
In looking at the characteristics of the lines, line 1 shows
Link Type = IEEE 802.3 CSMA/CD
Line 2 shows:
Examination of attributes shows:
Link Type = Vitalink Serial
Link Activation = True
From looking at the rest of the lines, it would appear that only active
lines that have been configured for Vitalink Serial show the CRC
counters.
Is this correct?

Yep. Give that man a raise.
If you skip to the bottom of my (probably overly long) reply in .3 you'll see
that only the Vitalink *SERIAL* lines return the CRC Errors counter; the
Ethernet ports don't.
