New Software Features in Cisco IOS Release 12.3(8)YH
The following features are supported by this release.
Inline Power Auto Negotiation
Inline power auto negotiation is supported.
Easy VPN Remote Web Based Activation
This feature provides user-friendly Web based entry of username/password via client web browser (IE or Netscape). A bypass mode is provided for Internet access without requiring VPN tunnel activation. One-time passwords are supported using RADIUS.
Limitations and Restrictions
Inline Power
The Cisco 1812 routers are able to deliver up to 80 W of power through Fast Ethernet switch ports if the routers are equipped with field-upgradable inline power daughter card and an external power supply. Up to eight IP phones may be powered by inline power.
USB
USB ports should not be connected to laptops or other hosts using Type A to Type A cables or connectors.
IPSec Tunnels
50 simultaneous IPSec tunnels are supported. A tunnel is defined as five SAs: one IKE, two AH and two ESPs. A data plane consists of ESP encapsulated in AH, encapsulated in IP.
Firewall
At least 4000 concurrent sessions are supported through the Cisco IOS firewall.
VLANs
A total of 8 VLANs can be configured on the 10/100BaseT ports.
Caveats
Caveats describe unexpected behavior or defects in the 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.
Open Caveats - Cisco IOS Release 12.3(8)YH
•
Traceback warning appears during callback on the auxiliary modem.
•
Sweeping ping packet drop for back-to-back Fast Ethernet
•
IPSec may cause performance degradation when unconfigured. IP CEF performance could be reduced only if IPSec is configured (and used) and then all the IPSec configuration is subsequently removed.
•
Router hangs after removing dialer pool-member from interface bri0.
•
Need to support SNMP traps for fan fault and overheating conditions.
•
ipv6ftp: Session counts are wrong after generating FTP alert.
•
Three tunnels are displayed when the show ipv6 pim tunnel command is issued.
•
pppox address negotiation using IPCP failed in an ipv6 RADIUS access test.
•
Occasional ALIGN-3-SPURIOUS, ALIGN-3-TRACE messages are displayed with pings.
•
The CEF Dialer failed to add adjacency for the CEF interface Virtual-Access1.
•
Packets enter in clear state.
•
Service exec-callback on the auxiliary port does not work.
•
The router crashed at stile_ad_show_all.
•
Show policy-map errors for match parameters occur.
•
CLI "clear line 5" does not clear active connection on the auxiliary line.
Resolved Caveats - Cisco IOS Release 12.3(8)YH
•
Cisco Internetwork Operating System (IOS) Software release trains 12.2T, 12.3 and 12.3T may contain vulnerabilities in processing certain Internet Key Exchange (IKE) Xauth messages when configured to be an Easy VPN Server.
Successful exploitation of these vulnerabilities may permit an unauthorized user to complete authentication and potentially access network resources.
This advisory will be posted to http://www.cisco.com/warp/public/707/cisco-sa-20050406-xauth.shtml

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

Information about Cisco products, technologies, and network solutions is available from various online and printed sources.
