---

New and Changed Information

The following section lists the new software features supported by the SOHO 70 Series routers for Release 12.2(1)XD4 and above.

New Software Features in Release 12.2(1)XD1

The following new software features are supported by the Cisco SOHO series for Cisco IOS Release 12.2(1)XD1 and above:

DHCP Server Import

The Cisco IOS Dynamic Host Configuration Protocol (DHCP) Server now allows a network administrator to enable Point-to-Point Protocol (PPP) to automatically configure the Domain Name System (DNS) and Windows Internet Name Service (WINS) Server IP address information within a Cisco IOS DHCP Server Pool(s). Enabling this automatic configuration works in conjunction with network access server commands that prevent a peer from receiving a negative acknowledgement (containing addresses for the peer to use), in response to an IP Control Protocol (IPCP) configuration peer request with non-zero addresses in the DNS and WINS options. (WINS is also known as the NetBios Name Server [NBNS].)

Configuring DHCP Server Import

Use the following commands to enable PPP to automatically configure the DNS and WINS Server IP address information within a Cisco IOS DHCP Server Pool(s).

•router(config-if)# ppp ipcp dns {request|reject|A.B.C.D.|accept}

Command Elements	Description
request	Request server addresses from the peer.
reject	Reject negotiations with the peer.
A.B.C.D.	Primary DNS IP address.
accept	Accept any non-zero DNS address.

•router(config-if)# ppp ipcp wins {request|reject|A.B.C.D|accept}

Command Elements	Description
request	Request server addresses from the peer.
reject	Reject negotiations with the peer.
A.B.C.D.	Primary WINS IP address.
accept	Accept any non-zero WINS address.

---

Note The above commands were introduced on the SOHO 70 Series Routers in Cisco IOS Release 12.2(1)XD.

---

IPCP Subnet Mask Delivery

Network administrators can assign IP address pools to customer premises equipment (CPE) devices, which, in turn, assign IP addresses to actual CPE and to a DHCP pool. This feature has three requirements:

•The Cisco IOS CPE device must be able to request and use the subnet.

•The Authentication, Authorization, and Accounting (AAA) Radius must be able to both provide that subnet and insert the framed route into the proper Virtual Route Forwarding (VRF) table.

•The provider edge (PE) router must be able to facilitate providing the subnet (via IPCP).

This functionality also exists in a non-Multiprotocol Label Switching (MPLS) environment if the CPE device is a Cisco 600 series router (which does not run Cisco IOS).

Configuring with IPCP Subnet Masks

Perform the following steps to configure your router to use IPCP subnet masks.

---

Note The commands described in the following steps were introduced on the SOHO 70 Series Routers in Cisco IOS Release 12.2(1)XD.

---

---

Step 1 Define an IP DHCP pool poolname using the global configuration commands below. For example:

Router(config)# ip dhcp pool IPPOOLTEST

Router(dhcp-config)# import all

Router(dhcp-config)# origin ipcp

The command import all imports the DHCP option parameters. The command origin ipcp configures the origin of the pool.

Step 2 Assign the Ethernet interface IP address using the command ip address pool poolname. For example:

Router(config-if)# ip address pool IPPOOLTEST

Step 3 Configure the dialer interface in the configuration interface command mode as follows:

a. Assign an IP address:

Router(config)# interface Dialer0

Router(config-if)# ip unnumbered Ethernet0

b. Set the IPCP negotiation parameters:

router(config-if)# ppp ipcp mask {request|reject|A.B.C.D}

Command Elements	Description
reject	Reject subnetmask negotiation from the peer.
request	Request the subnet mask from the peer.
A.B.C.D.	Subnet mask to provide to the peer.

---

The following sample shows a Cisco 827 router configured to use IPCP subnet masks:

Service Assurance Agent

The Service Assurance (SA) Agent feature is both a new name for and an enhancement to the Response Time Reporter (RTR) feature introduced in Cisco IOS Release 11.2. The response time and availability monitoring capabilities of RTR now include support for Voice over IP (VoIP), quality of service (QoS), and the World Wide Web.

The SA Agent is an application-aware synthetic operation agent that monitors network performance by measuring key metrics such as response time, availability, jitter (interpacket delay variance), connect time, throughput, and packet loss. This feature is intended to provide support for Service Level Agreement (SLA) reporting functionality of the Cisco VPN Solution Center, but can also be used for troubleshooting, for analysis before problems occur, and for designing future network topologies. Response Time Monitoring (RTTMON) functionality is supported.

Caveats

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.

Caveats in Cisco IOS Releases 12.2 and 12.2 T are also in Cisco IOS Release 12.2(1)XD4. For information on caveats in Cisco IOS Release 12.2, see Caveats for Cisco IOS Release 12.2. For information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS Release 12.2 T. These two documents list severity 1 and 2 caveats and are located on CCO and the Documentation CD-ROM.

Caveats for Release 12.2(1)XD1

This section describes possibly unexpected behavior by software Release 12.2(1)XD1.

Resolved Caveats for Release 12.2(1)XD1

This section describes possibly unexpected behavior by software releases prior to Release 12.2(1)XD1 that have been resolved in Release 12.2(1)XD1 and above.

CSCdt77246:

When a router is configured for PPPoE and IP NAT, and an incoming packet does not contain an MSS field or its TCP option field is not terminated by 0, the router might stop routing packets. This defect has been fixed in 12.2(1)XD1 release.

Unresolved Caveats for Release 12.2(1)XD1

This section describes possibly unexpected behavior by Release 12.2(1)XD1.

CSCdt92752

If you remove the current access-list from the encryption map, change the definition of the access-list, and then reassign the access-list to the encryption map, the access-list does not become active. Use the following solutions to work around this problem:

•To change a definition in the current access-list, directly change the access-list definition instead of removing the access-list from the encryption map.

•To assign a different access-list to the encryption map, remove the old access-list from the encryption map, assign the new access-list to the encryption map, and then define the new access-list.

For example:

crypto map map1 10 ipsec-isa

no match address 100

crypto map map1 10 ipsec-isa

match address 110

no access-list 110

access-list 110 permit ip host 2.0.1.26 host 4.0.1.25

CSCdt94260

While using the Dialer interface with Cisco Express Forwarding (CEF) enabled, when you connect a SOHO 70 series router to an access aggregator (such as a Cisco 6400 or Cisco 7200), Unicast Reverse Path Forwarding (URPF) incorrectly drops incoming ping packets from the access aggregator. This problem is caused by the Dialer CEF feature, which is on by default when CEF is enabled. To work around this problem, use the dialer interface command no ip route-cache cef to disable the Dialer CEF feature.

CSCdt95764

If you use the DHCP client feature to assign an encryption map to a Bridge Group Virtual Interface (BVI) before the BVI is up or active, the encryption map does not become active and an IPSec tunnel is not built. To work around this problem, assign the encryption map to the BVI again, after the BVI comes up. Note that rebooting the router alone does not fix the problem because the BVI is down before the reboot.

CSCdt98274

The command ip add dhcp client-id ethernet 0 is available under the BVI but cannot be applied after the DHCP client receives an IP address from the DHCP server. For example, if you enter the command ip address dhcp for BVI 1, then enter the command ip address dhcp client-id e0 on BVI 1 after the SOHO 70 router (the DHCP client) receives an IP address from the DHCP server, and follow up with the command show run, the following output is displayed:

!

 interface BVI1

  ip address dhcp

  crypto map map1

To work around this caveat, delete the existing IP address DHCP by entering the command no ip address dhcp. Enter the command ip address dhcp client-id ethernet 0, followed by the command ip address dhcp client-id ethernet 0.

Similarly, for the BV1 interface, if you enter the command ip address dhcp client-id ethernet 0 and, after the SOHO 70 Series Router (the DHCP client) receives an IP address from the DHCP server, you enter the command ip address dhcp for BVI 1, followed by the command show run, the following output is displayed:

!

 interface BVI1

  ip address dhcp client-id ethernet 0

  crypto map map1

To work around this bug, delete the existing IP address by entering the command no ip address dhcp client-id ethernet 0, and then issue a new IP address using the command ip address dhcp.

CSCdu02130

SOHO 70 series routers unexpectedly reload if you change the tranform set during an active IPSec tunnel and then clear the previous active IPSec tunnel. To work around this problem, clear the active IPSec tunnel before changing the tranform set for the active IPSec tunnel, then reapply the tranform set to the encryption map.
