TrustSec 3850 Specific Troubleshooting Information
Counters on the 3850 and 3650
The role-based counters command is broken on the 3850 and 3650, no data is ever displayed. This is fixed in release 16.6.1.
This is logged as DDTS CSCuu32958 (3850 "show cts role-based counters" not implemented platform limitation).
Prompt-3850#show cts role-based counters
Role-based IPv4 counters
# '-' in hardware counters field indicates sharing among cells with identical policies
From To SW-Denied HW-Denied SW-Permitted HW-Permitted
To get an idea of enforcement before the fix, use the following command on the 3850 and 3650:
Prompt-3850#show platform acl counters hardware | inc SGACL
Egress IPv4 SGACL Drop (454): 3 frames
Egress IPv6 SGACL Drop (455): 0 frames
Egress IPv4 SGACL Cell Drop (456): 0 frames
Egress IPv6 SGACL Cell Drop (457): 0 frames
If you have a 3850 stack then use the following command where the number signifies the stack member where the uplink resides:
Prompt-3850#show platform acl counters hardware switch 1 | inc SGACL
Egress IPv4 SGACL Drop (454): 4 frames
Egress IPv6 SGACL Drop (455): 0 frames
Egress IPv4 SGACL Cell Drop (456): 0 frames
Egress IPv6 SGACL Cell Drop (457): 0 frames
In Polaris code, use the following: show platform software fed switch x acl counters hardware
How to show Device Tracking Information on the 3850?
Prompt-3850#show ip device tracking all
Global IP Device Tracking for clients = Enabled
Global IP Device Tracking Probe Count = 3
Global IP Device Tracking Probe Interval = 30
Global IP Device Tracking Probe Delay Interval = 0

For Polaris code, use the following command: show platform software fed switch 1 ip route
How to Check if Global Enforcement is Enabled on the 3850?
Prompt-3850#show platform sgacl [detail]
Global Enforcement: On
For Polaris code, use the following command: show platform software fed switch 1 sgacl detail
How to Check if Enforcement is Enabled on the 3850 VLANs?
Prompt-3850#show platform sgacl vlan
Enforcement enabled:
vlan0 <----- Shows with global config of 'cts role-based enforcement'
vlan10
For Polaris code, use the following command: show platform software fed switch 1 sgacl vlan
How to Check the L2IF Configuration Settings of all Interfaces?
Prompt-3850#show platform sgacl port
Port Status Port-SGT Trust Propagate

Gi1/0/5 Enabled 0 No No
Gi1/0/6 Enabled 0 No No
etc

How to check/monitor inline tags on the 3850?
Polaris code supports the 'monitor capture' command, see the operation at the following link:
