• PCI 3 (decimal) / 0003 (hex) • Sales 4 (decimal)/ 0004 (hex) • HR 5 (decimal) / 0005 (hex) • SGA-Devices 6 (decimal) / 0006 (hex) • FinanceServers 7 (decimal) / 0007 (hex) • PublicServers 8 (decimal) / 0008 (hex) • DataBaseServer 9 (decimal) / 0009 (hex) Note SGT values are determined by the order in which the tag is created on the ISE server. SGT tags are assigned sequentially based on the order created in the tool. For example, Employees was entered first followed by PCI, Sales, <strong>and</strong> so on. Policy Component: IP to SGT Mapping This section demonstrates IP to SGT mapping on ISE. After the mappings are defined in ISE, the ISE deploys these mappings to the N7K. Note IP addresses are typically statically defined. This solution simplifies the data center use case to define SGT to IP mappings. 1. Go to Policy> Policy Elements > Results > Security Group Access > Security Group Mappings. Add the IP to SGT mappings illustrated in Figure 5-17 through Figure 5-19.
Figure 5-17. Adding the IP to SGT Mappings in ISE Figure 5-18. Adding Permissions Between Security Groups Defined in ISE Figure 5-19. Adding Permissions Between Security Groups Defined in ISE 2. Click the Check Status icon. ISE compares its SGT mapping to what is configured on the N7K, as illustrated in Figure 5-20. Currently, there is no configuration on the N7K; therefore, the result will be “Not Up to Date”.
