Tailoring an SNMP view for net-snmp 5.7.3, I fail to exclude IF-MIB::ifPhysAddress from my view: What ever I tried, I still get the MAC addresses in snmpwalk. Still I'm sure my view is being used as other excludes do work.

So here is my last attempt:

view publ included .iso.org.dod.internet.mgmt.mib-2 fc
# iso(1) org(3) dod(6) internet(1) mgmt(2) mib-2(1)

view publ excluded .1.3.6.1.2.1.2.ifTable.ifEntry.ifPhysAddress ff:c0
# 1 3 6 1 2 1 interfaces(2) ifTable(2) ifEntry(1) ifPhysAddress(6)
# .1.3.6.1.2.1.2.2.1.6

# this works:
view publ excluded .1.3.6.1.2.1.ip fe
# ip(4)

Update (2021-01-08)

The OID and mask given initially were wrong, causing error bad SUBTREE object id. Still, even with the fixed OID and mask the ifPhysAddress entries are still included in the view.

Update (2021-01-27)

I found out that using the symbolic names causes the problem: If I use only numeric IDs, it works.

Still, I don't know what causes the problem: The IF-MIB.txt is located in /usr/share/snmp/mibs, it contains the definitions being used, and it is included in the net-snmp-config --default-mibdirs.

This syntax is accepted, but the table column is not excluded:

view publ excluded IF-MIB::ifPhysAddress ff:c0

The problem turned out to be a non-issue; exactly it was a 1 vs. l font confusion: I had mixed view names vPubl and vPub1, but with the font being used in PuTTY, I didn't see the difference:
