Why does the Cisco 3560 over SNMP only return 15 instances of MSTP?

Question

Computer networks

Hello! Dear Cisco experts, tell me why the Cisco Catalyst 3560 over SNMP returns MSTP instances with numbers only less than 15?
The actual SNMP request:

[email protected]:~# snmpwalk -v 2c -c community ХХ.ХХ.ХХ.ХХ .1.3.6.1.4.1.9.9.82.1.11.12.1.3

Here's what it returns:

iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.2 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.3 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.11 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.13 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.15 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.23 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.26 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.1.28 = INTEGER: 2
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.12.2 = INTEGER: 2
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.12.28 = INTEGER: 4
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.13.2 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.13.23 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.13.26 = INTEGER: 3
iso.3.6.1.4.1.9.9.82.1.11.12.1.3.13.29 = INTEGER: 2

Instance 1, 12, 13 returns the correct ones, but for example 16, 18, 19 loses, although they are created and working on the switch.

Answer 1

This table is deprecated and replaced with stpxRSTPPortRoleTable.

It is necessary to request the updated oid 1.3.6.1.4.1.9.9.82.1.12.2.1.3.

Answer 2

With such specific questions it is necessary to write to the TP.
