Configure IP-SGT Bindings Manually

To configure IP-SGT bindings manually, perform the following steps:
Procedure
Step 1 Configure IP-SGT bindings manually.
cts role-based sgt-map [IPv4_addr | IPv6_addr] sgt sgt_value
Example:
hostname(config)# cts role-based sgt-map 10.2.1.2 sgt 50
The sgt sgt_value keyword-argument pair specifies the SGT number. Valid values are from 2-65519.

Troubleshooting Tips

Use the packet-tracer command to determine why a particular session was allowed or denied, which
SGT value is being used (from the SGT in the packet, from the IP-SGT manager, or from the policy
static sgt command configured on the interface), and which security group-based security policies were
applied.
The following example displays output from the packet-tracer command to show security group tag
mapping to an IP address:
hostname# packet-tracer input inside tcp inline-tag 100 security-group name alpha 30
security-group tag 31 300
Mapping security-group 30:alpha to IP address 10.1.1.2.
Mapping security-group 31:bravo to IP address 192.168.1.2.
Phase: 1
Type: ROUTE-LOOKUP
Subtype: input
Result: ALLOW

Use the capture capture-name type inline-tag tag command to capture only the Cisco CMD packets
(EtherType 0x8909) with or without a specific SGT value.
The following example displays output from the show capture command for a specified SGT value:
hostname# show capture my-inside-capture
