IP Session Recovery for DHCP-Initiated IP Sessions |
12.2(31)SB 12.2(33)SRC2 |
ISG provides a default policy and the ability to configure a policy that determines the actions ISG will take upon session restart following the recovery of a DHCP-initiated IP session. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. The following commands were introduced or modified by this feature: class type control, match vrf. |
IP Subscriber Session CLI Updates |
12.2(31)SB2 12.2(33)SRC |
Some of the commands that are used to configure ISG IP subscriber sessions were modified or replaced. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. The following commands were introduced or modified by this feature: clear ip subscriber, debug ip subscriber, identifier interface, identifier ip src-addr, initiator, interface multiservice, ip subscriber interface, ip subscriber, show ip subscriber. |
ISG: Instrumentation: DHCP Lease Query Support |
12.2(33)SRE 12.2(33)XNE |
The DHCP Lease Query transaction is a DHCP transaction with special message types that enable, among other things, clients to query DHCP servers regarding the owner and the lease expiration time of an IP address. In Cisco IOS Release 12.2(33)XNE, support was added for the Cisco 10000 series routers. |
ISG: Session: Creation: Interface IP Session: L2 |
12.2(28)SB 12.2(33)SRC 12.2SRE |
ISG IP interface sessions include all IP traffic received on a specific physical or virtual interface. IP interface sessions are provisioned through the CLI; that is, a session is created when the IP interface session commands are entered. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. |
ISG: Session: Creation: Interface IP Session: L3 |
12.2(28)SB 12.2(33)SRC 12.2SRE |
ISG IP interface sessions include all IP traffic received on a specific physical or virtual interface. IP interface sessions are provisioned through the CLI; that is, a session is created when the IP interface session commands are entered. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. The following sections provide information about this feature: |
ISG: Session: Creation: IP Session: Protocol Event (DHCP) |
12.2(28)SB 12.2(33)SRC |
Most ISG sessions are created upon detection of a data flow that cannot be affiliated with an already active session. An ISG can be configured to create an IP session upon receipt of the first DHCP DISCOVER packet received from a subscriber. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. |
ISG: Session: Creation: IP Session: Subnet and Source IP: L2 |
12.2(28)SB 12.2(33)SRC |
The ISG session is the primary component used for associating services and policies across specific data flows. An IP subnet session is an ISG session that includes any IP traffic from a single IP subnet. A source-IP-based session includes traffic from a single source IP address. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. |
ISG: Session: Creation: IP Session: Subnet and Source IP: L3 |
12.2(28)SB 12.2(33)SRC |
The ISG session is the primary component used for associating services and policies across specific data flows. An IP subnet session is an ISG session that includes any IP traffic from a single IP subnet. A source-IP-based session includes traffic from a single source IP address. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. |
ISG: Session: Multicast: Coexistence |
12.2(33)SRE |
The ISG Session Multicast Coexistence feature introduces the ability to host all the subscribers and services (data and multicast) on the same VLAN by enabling multicast and IP sessions to coexist on the same subinterface for Cisco 7600 series routers. In Cisco IOS Release 12.2(33)SRE, support was added for the Cisco 7600 router. |
ISG: Session: VRF Transfer: |
12.2(28)SB 12.2(33)SRC |
The ISG session is the primary component used for associating services and policies with specific data flows. ISG sessions are associated with virtual routing and forwarding instances when routing is required for the network service. ISG VRF transfer provides a means to dynamically switch an active session between virtual routing domains. In Cisco IOS Release 12.2(33)SRC, support was added for the Cisco 7600 router. |
ISG: Static Session Creation |
12.2(33)SRE 12.2(33)XNE |
The ISG Static Session Creation feature enables administrator-initiated static IP sessions. In Cisco IOS Release 12.2(33)SRE, support was added for the Cisco 7600 router. In Cisco IOS Release 12.2(33)XNE, support was added for the Cisco 10000 series routers. The following commands were introduced or modified by this feature: initiator static subscriber list,ip source,ip subscriber list,show ip subscriber static list. |
VRF-Aware Support for CoA Clients |
12.2(31)SB12 |
Allows one CoA client to support ISG subscribers in different VRFs. |
