Cisco Classic IOS Release Strategy

•
Cisco IOS Software Packaging
The Enterprise Services image supports all Cisco Catalyst 4500 Series software features based on Cisco IOS Software, including enhanced routing.
The IP Base image supports Open Shortest Path First (OSPF) for Routed Access, Enhanced Interior Gateway Routing Protocol (EIGRP) "limited" Stub Routing, Nonstop Forwarding/Stateful Switchover (NSF/SSO), and RIPv1/v2. The IP Base image does not support enhanced routing features such as BGP, Intermediate System-to-Intermediate System (IS-IS), Internetwork Packet Exchange (IPX), AppleTalk, Virtual Routing Forwarding (VRF-lite), GLBP, and policy-based routing (PBR).
The LAN Base image complements the existing IP Base and Enterprise Services images. It is focused on customer access and Layer 2 requirements and therefore many of the IP Base features are not required. The IP upgrade image is available if at a later date you require some of those features
Starting with Cisco IOS Release (3.3.0SG or 15.1(1)SG), support for IP SLAs and NSF have been extended from Enterprise Services to IP Base.

Cisco IOS XE to Cisco IOS Version Number Mapping
Upgrading the System Software
If you are upgrading to 3.3.0SG, you must upgrade your ROMMON to at least 15.0(1r)SG2
For details on the ROMMON upgrade process, refer to the "ROMMON Release Notes for the WS-X45-SUP7-E, WS-X45-SUP7L-E, and WS-C4500X Family of Switches". Note that you can upgrade a ROMMON image either through a console or telnet.
If they have dual supervisors, first upgrade your software to 3.3.0SG, then upgrade your ROMMON to 15.0(1r)SG2 to avoid the resets uplinks issue (CSCtj54375).
Identifying an +E Chassis and ROMMON
An +E chassis is identified by a FRU minor value in the chassis' idprom.
When supervisor engine 1 (sup1) is in ROMMON and supervisor engine 2 (sup2) is in IOS, only sup2 can read the idprom contents of chassis' idprom. Chassis type is displayed as "+E" in the output of the show version command. Conversely, sup1 can only display the chassis type as "E."
When both sup1 and sup2 are in ROMMON, both engines can read the chassis' idprom. Chassis type is displayed correctly as "+E" in the output of the show version command.
When both sup1 and sup2 are in IOS, both engines can read the chassis' idprom. Chassis type is displayed correctly as "+E" in the output of the show version command.
Limitations and Restrictions
These sections list the limitations and restrictions for the current release of Cisco IOS software on the Catalyst 4500E series switch.
•
•
•
•
•
•
•
TFTP numbers its datagrams with a 16 bit field, resulting in a maximum of 65,536 datagrams. Because each TFTP datagram is 512 bytes long, the maximum transferable file is 65536 x 512 = 32 MB. If both the TFTP client (ROMMON) and the TFTP server support block number wraparound, no size limitation exists.
Cisco has modified the TFTP client to support block number wraparound. So, if you encounter a transfer failure, use a TFTP server that supports TFTP block number wraparound. Because most implementations of TFTP support block number wraparound, updating the TFTP daemon should fix the issue.
•
The outputs of certain commands, such as show ip route and show access-lists, contain non-deterministic text. While the output is easily understood, the output text does not contain strings that are consistently output. A general purpose specification file entry is unable to parse all possible output.
Workaround (1):
While a general purpose specification file entry may not be possible, a specification file entry might be created that returns the desired text by searching for text that is guaranteed to be in the output. If a string is guaranteed to be in the output, it can be used for parsing.
For example, the output of the show ip access-lists SecWiz_Gi3_17_out_ip command is this:
Extended IP access list SecWiz_Gi3_17_out_ip10 deny ip 76.0.0.0 0.255.255.255 host 65.65.66.6720 deny ip 76.0.0.0 0.255.255.255 host 44.45.46.4730 permit ip 76.0.0.0 0.255.255.255 host 55.56.57.57The first line is easily parsed because access list is guaranteed to be in the output:
<Property name="access list" alias="Name" distance="1.0" length="-1" type="String" />The remaining lines all contain the term host. As a result, the specification file may report the desired values by specifying that string. For example, this line
<Property name="host" alias="rule" distance="s.1" length="1" type="String" />will produce the following for the first and second rules
<rule>deny</rule>and the following for the third statement
<rule>permit<rule>Workaround (2):
Request the output of the show running-config command using NETCONF and parse that output for the desired strings. This is useful when the desired lines contain nothing in common. For example, the rules in this access list do not contain a common string and the order (three permits, then a deny, then another permit), prevent the spec file entry from using permit as a search string, as in the following example:
Extended MAC access list MACCOYpermit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000 appletalkpermit any host 65de.edfe.fefe xns-idppermit any any protocol-family rarp-non-ipv4deny host 005e.1e5d.9f7d host 3399.e3e1.ff2c dec-spanningpermit any anyThe XML output of show running-config command includes the following, which can then be parsed programmatically, as desired:
<mac><access-list><extended><ACLName>MACCOY</ACLName></extended></access-list></mac><X-Interface> permit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000 appletalk</X-Interface><X-Interface> permit any host 65de.edfe.fefe xns-idp</X-Interface><X-Interface> permit any any protocol-family rarp-non-ipv4</X-Interface><X-Interface> deny host 005e.1e5d.9f7d host 3399.e3e1.ff2c dec-spanning</X-Interface><X-Interface> permit any any</X-Interface>CSCtg93278

A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2 uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting message, and the client marks the server as unresponsive.

•
Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different interface from the one used for media flow.
Workaround: None. CSCts20229

Resolved Caveats for Cisco IOS XE Release 3.3.2SG
This section lists the new resolved caveats for Cisco IOS XE Release 3.3.2SG:
•
Workaround: Reset the linecard either with the hw-module module m reset command or through a manual OIR. CSCuc64146
•

The power supply may go into an err-disable state if only one power supply has the issue. If both power supplies have the issue and are both recognized as 110V, they will not go into an err-disable state. Additionally, other modules in the switch might be denied power and will not power on.

Troubleshooting
These sections provide troubleshooting guidelines for the Catalyst 4500 series switches running IOS supervisor engines:
•
Netbooting from ROMMON
Netbooting using a boot loader image is not supported. Instead, use one of the following options to boot an image:
1.
rommon 1> boot slot0:<bootable_image>2.
The ROMMON TFTP boot is very similar to the BOOTLDR TFTP boot, except that:
–
–
To boot from ROMMON, perform the following tasks while in ROMMON mode:
a.
b.
c.
For example, to set the supervisor engine Ethernet port with an IP address 172.16.1.5 and IP mask 255.255.255.0, enter the following command:
rommon 2> set interface fa1 172.16.1.5 255.255.255.0d.
e.
f.
For example, to boot the Cisco IOS XE image cat4500e-universalk9.03.01.00 .SG.150-1.XO.bin located on the TFTP server 172.16.1.8, enter the following command:
rommon 3> boot tftp://172.16.1.8/tftpboot/cat4500e-universalk9.03.01.00 .SG.150-1.XO.binTroubleshooting at the System Level

Troubleshooting MIBs
For general information on MIBs, RMON groups, and traps, refer to the Cisco public MIB directory (http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml). For information on the specific MIBs supported by the Catalyst 4500 series switches, refer to the Catalyst 4000 MIB Support List located at ftp://ftp.cisco.com/pub/mibs/supportlists/cat4000/cat4000-supportlist.html.
