Release Notes for Cisco Network Assistant 3.0 and Later
January 30, 2006
These release notes include important information about Cisco Network Assistant 3.0, 3.0(1), and 3.1, and any limitations, restrictions, and caveats that apply to these releases.
This information is in the release notes:
When you install and launch Cisco Network Assistant 3.0, you can
•Receive notices of key network events, such as the availability of a new version of Cisco Network Assistant, an issue with a device in your network, or the need for a configuration change. The Event Notification window describes these events and, in many cases, helps you to respond appropriately.
•Specify security settings for hosts that are connected to Catalyst Express 500 switches by choosing low, medium, or high security in the Network Security window. The low setting (default) provides port security and protection against broadcast storms. The medium setting adds MAC address authentication. The high setting adds IEEE 802.1x authentication to permit or deny network connectivity and to control VLAN access based on user or machine identity.
•Apply Smartports roles to quickly configure Catalyst Express 500 ports for connections to desktops, IP phones, switches, routers, access points, printers, servers, guest devices, and diagnostic devices.
•Configure the wireless security settings of Cisco Aironet Access Points, like Service Set Identifiers (SSIDs) and Wired Equivalent Privacy (WEP), using the Secure Wireless window.
•Test the connectivity of any two devices, so long as one of them is a Catalyst Express 500 switch or one of them is directly connected to a Catalyst Express 500 switch.
•Navigate through network features more intuitively with a feature bar that is organized by major tasks: Configure, Monitor, Troubleshoot, and Maintenance. Keyboard shortcuts are also available for easy navigation.
•View a report that has details about the connections between Catalyst Express 500 switches and their neighbors.
•Search for a port by entering a MAC address, an IP address, or a description.
•See the percentage of bandwidth utilized on Catalyst Express 500 switches in the past minute, hour, day, or 2-week period.
The system requirements are described in these sections:
The PC on which you install Network Assistant must meet these minimum hardware requirements:
•Processor speed: Pentium 3, 1 GHz
•DRAM: 256 MB
•Hard-disk space: 200 MB recommended (the actual application requires around 70 MB)

Note The Topology view of Network Assistant supports Catalyst 6500 switches. You cannot add these devices to a community or cluster, but you can launch device manager for them from the Topology view.
Cisco Aironet 350, 1100, and 1200 series. Network Assistant supports them only if they run a Cisco IOS image.
Cisco PIX 515E Firewalls
Note PIX Firewalls do not support the Cisco Discovery Protocol, so they are not automatically shown as neighbors in the Topology view. They are shown only after you add them to a community by using a Create Community or Modify Community window. To see a PIX Firewall link to another community member, you must add the link manually by selecting Add Link in a Topology popup menu.
This section describes how to choose command and standby command devices when a cluster consists of a mixture of Catalyst switches. When creating a device cluster or adding a devices to a cluster, follow these guidelines:
•When you create a device cluster, we recommend configuring the highest end device in your cluster as the command device.
•If you are managing the cluster through Network Assistant, the device that has the latest software release should be the command device.
•The standby command device must be the same type as the command device. For example, if the command device is a Catalyst 3750 switch, all standby command devices must be Catalyst 3750 switches.
Note Catalyst 4500 series switches cannot be configured as standby command devices.
Downloading Network Assistant
You can download Network Assistant from this site:

Limitations and Restrictions
You should review this section before you begin working with the device. These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the device hardware or software.
These sections describe the limitations and restrictions:
Cluster Limitations and Restrictions
These limitations apply only to the Catalyst 4500 series switches:
•By default, clustering is disabled on the Catalyst 4500 series switches.
•You must assign an IP address to the Catalyst 4500 series switch if it is a cluster command switch candidate. If the switch is a cluster member candidate, you might not need to assign an IP address.
•By default, the HTTP server is disabled on the Catalyst 4500 series switch. To connect the switch to Network Assistant, you must enable the HTTP server on all cluster members.
•The HTTP port number on Network Assistant and the Catalyst 4500 series switch must match.
•A Catalyst 4500 switch can be a cluster member only if another Catalyst 4500 switch is the command device.
•By default, the Catalyst 4500 series switch is configured with five vty lines. If the switch (such as a cluster command device with multiple cluster members) is connected to Network Assistant, you must configure at least eight + x vty lines, where x is the number of vty lines used by other applications. A maximum of 16 vty lines can be configured.
•Create a switch virtual interface (SVI) to use for intracluster communication. The SVI must be in the no shut state.
This limitation applies only to the Catalyst 4500 series and Catalyst 3750, 3560, 3550, and 2970 switches:
•If a Catalyst 2900 XL or 3500 XL cluster command device is connected to a Catalyst 3550 or a 3750 switch, the command device does not find any cluster candidates beyond the 3550 or the 3750 switch candidates. You must add the 3550 or the 3750 switch to the cluster to see other cluster candidates. (CSCdt09918)
These limitations apply only to the Catalyst 3750, 3560, 3550, and 2970 switches:
•If both the active command device and the standby command device fail at the same time, the cluster is not automatically recreated. Even if there is a third passive command device, it might not recreate all cluster members because it might not have all the latest cluster configuration information. You must manually recreate the cluster if both the active and standby command devices simultaneously fail. (CSCdt43501)
•When the active device fails in a device cluster that uses Hot Standby Routing Protocol (HSRP) redundancy, the new active device might not contain a full cluster member list.
The workaround is to ensure that the ports on the standby cluster members are not in the Spanning Tree Protocol (STP) blocking state. See the "Configuring STP" chapter in the software configuration guide for more information about verifying port status. (CSCec31495)
These limitations apply only to the Catalyst 2955, 2950, and 2940 switches:
•When a cluster of devices have Network Time Protocol (NTP) configured, the command device is not synchronized with the rest of the devices. (CSCdz88305)
Network Assistant Limitations and Restrictions
The Network Assistant limitations and restrictions are described in these sections.
These limitations apply to all the devices described in the "Devices Supported" section:
•A red border appears around the text-entering area of some Network Assistant windows. The color of the border changes to green when text is entered. The colored border does not prevent you from entering text. (CSCdv82352)
•You cannot switch modes (for example, from guide mode to expert mode) for an open Network Assistant window. The workaround is to close the open window, select the mode that you want, and then reopen the Network Assistant window. For the mode change to take effect on any other Network Assistant window that is open, you need to close that window and then reopen it after you select the new mode. (CSCdw87550)
•If you open a window in which you can enter text, open another window, and return to the first window, right-clicking in the text field might make the cursor in this field disappear. You can still enter text in the field. (CSCdy44189)
•If you select multiple ports and open the Port Settings window from the popup menu of the Front Panel view, it might take approximately 7 seconds to open.
The workaround is to open the Port Settings window from the feature bar. (CSCee96650)
•When the active device fails in a device cluster that uses HSRP redundancy, the new active device might not contain a full cluster member list.
The workaround is to ensure that the ports on the standby cluster members are not in the STP blocking state. See the "Configuring STP" chapter in the software configuration guide for information about verifying port status. (CSCec31495)
•When there are more than one neighbor devices of same device type and they have same hostname, the Topology view displays only one neighbor device instead of displaying all the neighbor devices.
The workaround is to not have same hostname for more than one device. (CSCsb50280).
Catalyst 4500 Series Switches
On Catalyst 4500 series switches, Network Assistant supports only the features shown in Table 2:
This limitation applies to the Catalyst 4500 Series Switches:
•In Network Assistant, some windows such as VLAN, Hostname, and so on might not open from the Front Panel view popup menu for Catalyst 4500 series switches.
The workaround is to close Network Assistant and restart it. (CSCef67553)
These limitations apply only to communities:
•A community can contain up to 20 devices. This limit is enforced whenever you add devices to a community.
Furthermore, a community cannot contain more than 16 nonmodular switches, 4 modular switches, 12 access points, and 2 routers. These limits are checked during the launch of Network Assistant; you receive a warning if they are exceeded.
•Changes to the topology or network do not propagate across all open Network Assistant sessions connected to the same community. You see this inconsistency when multiple Network Assistant sessions are open on one desktop, and they point to the same community.
Open one Network Assistant session per desktop per community. (CSCeh53619)
•The Topology view sometimes displays duplicate devices and links. There is no workaround. (CSCeh61352)
•In the Topology view, the horizontal scrollbar sometimes does not scroll far enough left to show the complete topology. The workaround is to right-click the Topology view and to select Automatic Topology Layout from the popup menu. (CSCeh56952)
•In the Topology view, if there are multiple links between community members and one of the links is blocked, it is shown in green, not in gray. There is no workaround. (CSCeh60050)
•In the Topology view, the redundant link for an HSRP group is not shown. There is no workaround. (CSCeh54526)
•If a community has members that are connected to a member through a hub or a Gigastack module, the Topology view shows all the connections. But if nonmembers are connected to a community member through a hub or a Gigastack module, the Topology view shows only the connection of the first nonmember.
•Accessing a community through a router running NAT (Network Address Translation) is not supported.
These limitations apply only to clusters:
•When you add a new member with a username and password that is different from the existing cluster member usernames and passwords, Network Assistant produces an exception error because of an authentication failure. The workaround is to add the new member without a username and password. When the new member is added to the cluster, remove the existing username and password from the Username and Password fields, enter a new username and password, and then apply it to all cluster members. (CSCdz07957)
•Changing the password or current authentication while Network Assistant is running causes HTTP requests to fail. The workaround is to close all Network Assistant sessions and then to restart it. (CSCeb33995)
•When TACACS authentication is enabled only on a command device, member devices cannot be configured. The workaround is to enable TACACS authentication on the member devices. (CSCed27723)
•When there are Catalyst 2950 and 2955 devices in a cluster, and you launch the QoS Queue window to configure the devices, and then try to view the settings for other devices by using the device selection menu, Network Assistant halts after 20 to 30 selections.
The workaround is to close and then to restart Network Assistant. (CSCed39693)
•A Java exception error occurs when Network Assistant is in read-only mode and you launch the Port Settings window. This only occurs on Catalyst 3500 XL, 2950 LRE, and 2900 XL switches.
The workaround is to open the Port Settings window with Network Assistant in read-write mode. (CSCee25870)
Community and Cluster Limitations
These limitations apply to both communities and clusters:
•Network Assistant fails when a device is running the cryptographic software image and the vty lines have been configured with the transport input ssh and line vty 0 15 global configuration commands to use only SSH. The workaround is to use the transport input ssh telnet and line vty 0 15 global configuration commands to allow SSH and Telnet access through the vty lines. (CSCdz01037)
•When the Link Graphs application has run for hours displaying packet drop and error information, sometimes the X-axis crosses the Y-axis at a negative Y value instead of at Y= 0. This condition occurs with all supported operating systems, browsers, and Java plug-ins. There is no workaround. (CSCdz32584)
•After you click Apply or Refresh in the Simple Network Management Protocol (SNMP) window, the window size changes. (CSCdz75666, CSCdz84255)
•When you enable log scaling for Link Graphs, the Y-axis scale becomes illegible. There is no workaround. (CSCdz81086)
•If an access control list (ACL) is deleted from a device, all QoS classes on Catalyst 2970 and 3750 switches that use this ACL for traffic classification become unusable. The modification of these classes to use any other traffic classification (match statement) fails. The workaround is to delete the QoS class that uses the undefined ACL and then to recreate it with the intended traffic classification (match statement). (CSCed40866)
•When an Open Shortest Path First (OSPF) summary address is added for a 10.x.x.x network, a Windows exception error sometimes occurs.
The workaround is to add the address by using the router ospf <process-id>, area <area-id>, and range <address> <mask> configuration commands. (CSCed87031)
•Hostnames and Domain Name System (DNS) server names with commas for a cluster command device, member device, or candidate device can cause Network Assistant to behave unexpectedly. You can avoid this instability in the interface by not using commas in hostnames or DNS names. Do not enter commas when also entering multiple DNS names in the IP Configuration tab of the IP Management window in Network Assistant.
•Access control entries (ACEs) that contain the host keyword precede all other ACEs in standard ACLs. You can reposition the ACEs in a standard ACL with one restriction: No ACE with the any keyword or a wildcard mask can precede an ACE with the host keyword.
•When you reload a device with Network Assistant, it saves the running configuration. If you want to reload without saving the running configuration, use the CLI. (CSCeh24259)
These sections contain important notes related to Network Assistant:
Compatibility with Cisco IOS
If you run Cisco IOS 12.2(25)SEE or later or Cisco IOS 12.1(22)EA7 or later, you must run Network Assistant 3.1 or later.
This note applies to community on all the devices described in the "Devices Supported" section:
All the devices for the topology of a community are derived from the CDP (Cisco Device Protocol) table of Cisco IOS. Therefore, the Topology view shows duplicate devices when CDP discovers duplicate devices. This happens for a single device when the command show cdp neighbor is entered. Two devices are displayed: one with the actual hostname (for example, abc), the other with hostname.domainname (for example, abc.cisco.com).
This note applies to cluster configuration only on the Catalyst 3550 switches:
The cluster setup privileged EXEC command and the standby mac-address interface configuration command have been removed from the command-line interface (CLI) and the documentation because they did not function correctly.
Network Assistant Notes
These notes apply to Network Assistant configuration on all the devices described in the "Devices Supported" section:
•If you use Network Assistant on Windows 2000, it might not apply configuration changes if the enable password is changed from the CLI during your Network Assistant session. You have to restart Network Assistant and enter the new password when prompted. Platforms other than Windows 2000 prompt you for the new enable password when it is changed.
•Network Assistant does not display QoS classes that are created through the CLI if these classes have multiple match statements. When using Network Assistant, you cannot create classes that match more than one match statement. Network Assistant does not display policies that have such classes.
•Within an ACL, you can change the sequence of ACEs that have the host keyword. However, because such ACEs are independent of each other, the change has no effect on the way the ACL filters traffic.
•In the Front Panel view or Topology view, Network Assistant does not display error messages in read-only mode for these devices:
–Catalyst 3550 member switches running Cisco IOS Release 12.1(6)EA1 or earlier
–Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier
–Catalyst 2900 XL or 3500 XL member switches running Cisco IOS Release 12.0(5)WC2 or earlier
In the Front Panel view, if the device is running one of the software releases listed previously, the device LEDs do not appear. In Topology view, if the member is an LRE switch, the CPE devices that are connected to the switch do not appear. The Bandwidth and Link graphs also do not appear in these views.
These sections describe the open caveats that could create possibly unexpected activity in this software release.
These caveats apply to all the devices described in the "Devices Supported" section:
If Network Assistant loses IP connectivity to the switch and an action is performed in the IP Address window, a Java exception error occurs.
The workaround is to close and to reopen the IP Address window when connectivity is restored.
After a cluster member loses connectivity, the connect icon in the status bar incorrectly displays a connect status instead of a disconnect status.
There is no workaround.
The Network Assistant window flickers if you click Cancel in the Application > Print window.
There is no workaround.
If a Catalyst 2970 switch is a cluster command device and a Catalyst 3750 or 3550 switch is a cluster member, enabling IGRP on a network on the Catalyst 3750 or 3550 switch creates a Premature EOF error.
There is no workaround. Make the Catalyst 3750 or 3550 switch the command device.
After you click Finish, you see the commands that are actually applied to the device.
Access points and routers are not supported in the Front Panel view, but sometimes the check boxes for these devices are checked, even if they are grayed out.
There is no workaround.
In the Link Graphs window, when you choose the Packet Drops & Errors option for a Catalyst 4500 or 4900 switch, you see inaccurate link traffic statistics.
There is no workaround.
If you change the default setting of the Graph Display Type in the Bandwidth Graph window, the change is not retained for your next use of the window.
Check that the Graph Display Type setting is what you want whenever you use the window.
The Smartports Port Setup window does not show the LED status of the ports.
You can use the window to configure ports even if status information is not shown.
When you select a VLAN and assign an aging time in the MAC Addresses window, if you check Apply to Other VLANs, the box does not remain checked.
The aging time is nevertheless applied to all the VLANs.
If a dual-media port on a Catalyst 4500 switch, model WS-C4948 or model WS-X4506-GB-T, is configured to RJ-45 and you apply a Smartports port macro, the port is changed to SFP, the default setting. The connection to the port is lost.
Reconfigure the media type to RJ-45 through the Port Settings window.
If you change a hostname while a Network Assistant window is open, the window might not display the new hostname, even if you refresh the window.
To see the new hostname, close the window and then reopen it.
The Media Type column in the Port Settings window appears even if the modules of a Catalyst 4500 switch do not support AWP (alternate wired ports). If this case, the column fields display as N/A.
There is no workaround. The other columns in the window are not affected.
In the Port Settings window, you must apply a change to some speed settings before you can change a duplex setting.
After you configure a speed setting, click Apply; then configure a duplex setting.
If you try to close Network Assistant while a task is running, Network Assistant asks whether you really want to exit but does not say what might happen if you do.
Decide whether an important task is in progress. If it is, answer by clicking no.
The Security Wizard sometimes does not show a warning message when it applies an ACL to a port that already has an ACL applied to it.
There is no workaround.
In a Topology view for a community, the link icons for routed, trunk, and Gigastack links are not shown.
There is no workaround.
When you create an enable password through Network Assistant, you create an enable secret (encrypted) password. Therefore, no entry for the password appears on the Enable Password tab of the Users and Passwords window.
If you do not want to create an encrypted password, the workaround is to use the CLI to create a nonencrypted password. Network Assistant will prompt users for this password when they connect, even though the password does not appear on the Enable Password tab.
Even if you see the message Port security is only supported on static access interfaces, it is also supported on ISL trunk ports and IEEE 802.1Q trunk ports if these ports are supported by the Cisco IOS image.
The Port Security window lists all the ports that are eligible for port security. If a port is not listed, configure the port as necessary through the VLAN window, and return to Port Security window to configure the port security settings.
When the media type is changed on a S-X4506-GB-T linecard through the CLI or through another instance of Network Assistant, your instance of Network Assistant might be put into an inconsistent state, resulting in a blank Port Settings window.
The workaround is to close your instance of Network Assistant and then restart it. You can then use the Port Settings window without a problem.
You cannot see the PoE columns in the Port Settings window for Catalyst 4503, 4506, or 4507R switches that run Cisco IOS 12.2(20)EWA and have a WS-4548, WS-4524, or WS-4506-GB-T PoE line card.
The workaround is to upgrade the software on the switch to a later version of Cisco IOS.
If you open the Modify Port Settings or the Modify Port Mode window twice in succession from the Front Panel view by right-clicking a port, selecting Port Settings or VLAN from the popup menu, and repeating these actions for another port, the windows display the settings for the port that you selected first.
Ensure that the Interface field in these windows applies to the port that you selected. Be sure to close these windows between port selections.
If you cancel the printing of the Topology view, its background turns white.
There is no workaround.
After you perform a search, the TAB key moves the focus in the search results. If you press the TAB key enough to reach the end of the results, the next TAB keystroke moves the focus out of the search results and into the next-in-focus window on the Network Assistant desktop.
Press ALT-s to return to the search results.
If you set the configuration bits through the CLI to 0x2100 or 0x2101 and then restore a configuration with the Configuration Archive window, you might not be able to reload the device.
Set the configuration bits to 0x2102, and specify a boot variable through the CLI.
A device is counted more than once in determining whether the community limits have been exceeded if the device has multiple IP addresses and more than one of these IP addresses has been added to the community.
To remove the additional IP addresses, follow these steps:
1. Select Application > Communities.
2. Select a community, and click Modify.
3. Select the additional IP addresses, click Remove, and then click OK.
4. Click OK in the Communities window.
Zooming in or zooming out on the time axis of a bandwidth graph when the axis approaches noon or midnight might cause the time increments to be incorrectly labeled.
Close the Bandwidth Graph window, reopen it, and zoom in or out again.
If you change the hostname of a community member in a Network Assistant session and then try to change it in a session with a different community, you see a message that the name change failed. However, the name change is actually successful.
There is no workaround.
On Catalyst 4500 and 4900 series switches, you cannot edit flow control values from the Port Settings window; they are read-only.
The workaround is to open the Front Panel view, right-click on the port to be configured, and select Port Settings from the drop-down list. From the Modify Port Settings window, you can configure the flow control values.
Network Assistant does not verify if the VLAN and the native VLAN are the same on the access point and the switch port that is connected to the access point. VLAN differences might cause wireless connectivity problems when you use the Secure Wireless feature.
The workaround is to ensure that the VLANs and the native VLAN are the same on the access point and the switch port.
On a Catalyst 4500 or Catalyst 4900 series switch, when you select Security > Port Security and try to associate a secure address with a trunk port, an "Invalid input detected" error is displayed.
There is no workaround for a trunk port. Open the VLANs window, select the device and port, click Modify, and select an administrative mode that is not for a trunk port.
When you connect to Network Assistant in read-only mode, choose Configure > Port > Port Settings on the feature bar, and select a Catalyst 4500 series switch, you are prompted to request level-15 access. This is the read/write access level, which is incompatible with read-only mode. You cannot view the Port Settings window.
The only workaround is to get permission from your administrator to connect to Network Assistant in read/write mode.
Upgrading the Cisco IOS software on a device to a cryptographic image from an noncryptographic image is not sufficient to make an HTTPS connection with the device.
After the upgrade, remove the device from the community, configure it for HTTPS, and add it back to the community. You can then use HTTPS to communicate with the device.
These caveats apply to Cisco EtherSwitch service modules:
The Front Panel view on EtherSwitch service modules NME-16ES-1G-P, NME-X-23ES-1G-P, NME-XD-24ES-1S-P, and NME-XD-48ES-2S-P shows the EN-LED as not enabled.
There is no workaround.
The Topology view does not show the internal Gigabit Ethernet link between routers and the EtherSwitch service modules NME-16ES-1G and NME-X-23ES-1G.
There is no workaround.
The Smartports window shows the NME-XD-24ES-1S-P EtherSwitch service module with two Mode buttons instead of one
There is no workaround.
This section describes the resolved caveats.
Caveats Resolved in Network Assistant 3.1
These caveats were resolved in Network Assistant 3.1
Network Assistant now recognizes WS-X4306-GB linecards whose firmware is 2.0 or lower.
On Catalyst Express 500 switches, you can now associate a Cisco-Voice VLAN with a Smartports role other than IP Phone.
Caveats Resolved in Network Assistant 3.0(1)
These caveats were resolved in Network Assistant 3.0(1):
When you apply a Smartports role to a Catalyst 4500 or 4900 switch, the switch no longer resets or switches over to the standby supervisor, regardless of the Cisco IOS version that it runs.
If you manage a Catalyst 2900 XL switch as a standalone device, Network Assistant now shows its links to neighbor devices in a Topology view. If you manage it in a community, you can now see a popup window in the Topology view when you right-click one of its links.
Cisco IP phones that do not appear in the Topology view will appear when their firmware is upgraded.
If you change the network security settings on Catalyst Express 500 community members from low to medium, hosts originally connected at the low setting can now reconnect to the network after they are disconnected or shut down.
Caveats Resolved in Network Assistant 3.0
These caveats were resolved in Network Assistant 3.0:
After the cluster command device is reloaded, it can now re-establish communication with the cluster members connected through its routed ports.
In the columns of the Inventory window, when you click the arrow that shows ascending sorting (an arrow pointing downwards) or the arrow that shows descending sorting (arrow pointing upwards), the results are no longer incorrect. This also applies to all the other feature windows that have ascending and descending arrows.
Changing the severity criteria for notifications of some system messages no longer causes changes to the criteria for other system messages.
You can now upgrade Cisco IOS software with a third-party TFTP server by using the remote TFTP option of the Software Upgrade feature. However, we recommend that you select the standard mode option so that you can use the Network Assistant embedded TFTP server.
Network Assistant now displays an error if you lose connectivity to a device while Network Assistant is saving or backing up its configuration.
Network Assistant now displays an error if there is not enough hard-disk space to allow a backup to succeed.
Network Assistant now displays an error if there is not enough flash memory in the device to save a configuration.
Network Assistant now displays the configured HTTP port number for devices that run Cisco IOS 12.1.
A community member no longer becomes unmanageable if its Cisco IOS image is changed from a cryptographic image to a noncryptographic image.
The port colors on the Front Panel view are no longer inaccurate when ports on Catalyst 2950, 3550, and 3750 switches are set to half duplex.
You can now change the default HTTP port number from 80 to another value by using Network Assistant on a switch running Cisco IOS 12.2(20)EWA or later.

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:
•For Emergencies only — email@example.com
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•For Nonemergencies — firstname.lastname@example.org
In an emergency, you can also reach PSIRT by telephone:
•1 877 228-7302
•1 408 525-6532
Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:
The link on this page has the current PGP key ID in use.
If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

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)—An existing 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 operations 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 the network is impaired, while 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.
