Cisco MATE and WAE 6.1.7 Release Notes

Cisco MATE Design

EIGRP routing simulation is not accurate. This issue will be corrected in a future release. Until then we recommend that it not be used.

Cisco MATE Live

• L2 interface types are categorized incorrectly as “individual physical interfaces” on the Explore Interfaces page.
• The “Unknown” interface type is not used.
• You cannot create a network from the UI upon initial startup. The workaround is as follows:

1. Stop the web server.

2. Restart the web server from a directory that has permissions for the WAE user specified during installation. Use the following command:

Cisco MATE Collector

Due to vendor MIB limitations, Cisco MATE Collector cannot represent QoS traffic on interfaces that have more than one VLAN configured. If a network contains such interfaces, their queue traffic statistics are omitted from the collection. The total traffic on these interfaces is still measured. As a result, per class-of-service demands estimated through Demand Deduction are less accurate. Estimates of traffic totals over all classes of services, however, are not affected.

Collector Server

• The Collector server does not make plan files available. The workaround is to delete the snapshot directories from previous releases. These are in $CARIDEN_ROOT/data/collector/server/snapshots.
• If upgrading the Collector server from 5.6x to 6.1x, the $CARIDEN_ROOT/etc/collector/server/db-persistence/DiscoveryEngineImplementation.db file must be removed prior to starting the web server. Since installation automatically starts the web server, the recommendation is to remove this prior to installation. If you forget to do so, after installation, stop the web server, remove this file, and then restart the web server.
• OSPFv.2 databases cannot be collected via SNMP. The workaround is to use a manual snapshot.
• OSPFv.3 and IPv6 IS-IS databases cannot be collected. The workaround is to use a manual snapshot.
• SNMPv.3 device access is not supported. The workaround is to use a manual snapshot and run mate_auth_init.

Snapshots

• snmp_find_interfaces

– Does not support association of GRE tunnel with the physical interface it uses to reach the tunnel destination since the IP-Tunnel MIB lacks this information.

– Does not update LAG port status if LAGs are discovered running both parse_configs and snmp_find_interfaces. The workaround is to run only snmp_find_interfaces.

• Juniper routers: Signaled standby LSP path option is not available from the standard MPLS-TE MIB for Juniper routers. Only the active path option name is collected.
• IOS XR routers

– IGP topology collected through parse_igp and login_find_igp_db.

• IS-IS link-state database with TE extensions contains incorrect interface “admin-weights” (TE metric) on Intel-based routers.
• IPv6 IS-IS link-state database does not contain IPv6 interface addresses or parallel interfaces. This information is only available when IOS XR supports IS-IS IPv6 TE extensions. The snmp_find_interfaces tool collects this information.

– MAC Accounting is not supported.

– snmp_find_rsvp does not set the Standby value in the <LSPPaths> table for signaled backup paths.

• BGP peers

– find_bgp does not build BGP pseudo-nodes among internal ASNs.

– find_bgp does not collect BGP peers under PE-CE VRFs.

• parse_configs does not accurately detect the bandwidth of some Juniper ‘ge’ interfaces that have a capacity of 10 Gbps.
• TE Extended Admin Groups (EAGs), also known as extended affinities, are not supported.
• Port circuits are not built for LAG/bundle members whose nodes are not within the same IGP instance as the AS.

SAM-OSS Integration with Snapshots

• sam_getplan does not populate the <NodeTraffic> table. This table is derived and populated when sam_getplan and SNMP tools are used together.
• sam_getplan does not populate the NetIntActivePath column in the <LSPs> table.
• If sam_getplan and SNMP tools are used together in the snapshot process for multivendor network collection, then Alcatel-Lucent traffic measurements cannot be aligned with those collected from other router platforms.

Cisco WAE Core

When creating tunnels with REST APIs, both primary and secondary tunnels are set to Standby.

System

Web User Management

Both the System UI and the MATE Design Archive UI have user management capabilities. If both are used to configure users, MATE uses the most recently updated information. The recommendation is to use only the System UI to manage users.

Starting MATE Design in Linux

The $CARIDEN_HOME directory is not automatically added to $PATH (only $CARIDEN_HOME/bin is). If not in $CARIDEN_HOME/bin, to start the MATE GUI from the command line, you must specify its full path:

WAE High-Availability

The wae-ha-deploy script is not updated with the proper version, rendering the wae-core modules unable to start in a multiserver (HA) environment. The workaround is as follows:

1. Modify the /wae-platsvcs/confmgmt/roles/wae-core/templates/org.apache.karaf.features.cfg.j2 file on the primary node, as follows.

Change this line:

to:

2. Run the wae-ha-deploy script.

License Check Failures on Newer Linux Distributions

Some newer Linux distributions have started using a new way (via biosdevname) of naming hardware devices, including the network interfaces. This causes some software that depends on the traditional naming (for example, eth0, eth1) to fail on license checks, including MATE.

The workaround is to append biosdevname=0 to the kernel line of the grub configuration file and reboot. (Syntax varies among distributions.)

After reboot, you should be able use ifconfig to verify that the NIC are named eth0 (or eth1,...) instead of the biosdevname names (such as p34p1).

Java Memory

Certain tools (such as sam_getplan and parse_configs, for example) may require more memory to start than what is available. The symptom is an error message similar to the following:

The workaround is to set the maximum memory to a low enough value in the CARIDEN_JAVA_OPTIONS variable before calling the tool. An example setting is as follows:

Documentation

The following information is missing from the documentation set. For assistance, contact your support representative.

• Multinetwork discovery
• Cisco MATE Live

– New feature updates in the Cisco MATE Live User Guide

– Making plan files from multiple networks available to the MATE Live UI

• Cisco WAE Platform Configuration Guide, Manual Collection with Continuous Polling chapter

– statsComputingMinimumWindowLengthInSecs example needs a minor change. For convenience, the entire definition and example are given here:

statsComputingMinimumWindowLengthInSecs—Defines the minimum amount of time, in seconds, over which to generate averages of the polled traffic statistics. For example, if set to 300, to determine the rate of incoming packet errors, the Continuous Poller server takes the average of these incoming packet errors over the last 300 seconds. These traffic statistics are added to the plan file each time it is generated. The minimum value is 300 seconds.
