HI Shahzad,
If you wants full DNS appliance or DHCP support or GSLB for other DNS record types, order the Cisco GSS DNS license (SF-GSS-DNSLIC) plus the Cisco Network Registrar software (CNR-6.3-BASE1K is the recommended base Cisco Network Registrar software for the Cisco GSS).
The Cisco GSS DNS software license allows you to load Cisco Network Registrar software onto your Cisco GSS 4492R, which transforms the Cisco GSS 4492R into a standards-compliant DNS and DHCP appliance that offers a very advanced feature set, including support for incremental zone transfers, dynamic updates, and notification. The Cisco Network Registrar DHCP server supports DHCP Safe Failover (redundant DHCP servers), dynamic DNS updates, DOCSIS cable modems, and integration with directory services using Lightweight Directory Access Protocol Version 3 (LDAPv3).
Note:
• Cisco Network Registrar software must be acquired separately. You must load Cisco Network Registrar Release 6.3 or higher on the Cisco GSS device to get the additional DNS and DHCP capabilities
• Cisco GSS Software Release 2.0(2) or higher must be loaded on the Cisco GSS device.
