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 might have identified a
vulnerability in a Cisco product, contact PSIRT:

• Emergencies— [e-mail]

• Nonemergencies— [e-mail]

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive

information that you send to Cisco. PSIRT can work from encrypted information that is compatible with
PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence
with PSIRT is the one that has the most recent creation date in this public key server list:

http://pgp.mit.edu:11371/pks/lookup?search=psirt%40cisco.com&op=index&exact=on

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

• 1 408 525-6532

Obtaining Technical Assistance

Search results show an illustration of your product with the serial number label location highlighted.
Locate the serial number label on your product and record the information before placing a service call.

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: [phone] (Australia: 1 800 805 227)
EMEA: [phone]
USA: 1 800 553-2447

For 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.

2.3(3):

<INSTALLDIR>/mmtsys/sys/events.log

<INSTALLDIR>/mmtsys/sys/rmspolld.log

<INSTALLDIR>/httpd_perl/logs/error_log

Solaris Installation Instructions

To install the CMM for Solaris 2.8 or Solaris 2.9, log in as the root user and follow one of the approaches
outlined below.

Note Approximately 300MB of disk space is required for installation.

1. Install the CMM in the following directory:

/opt/RMSMMT

If there is not enough room in the /opt directory, create the RMSMMT directory on another partition
and create a symbolic link to it from /opt. For example:

# mkdir /space/RMSMMT
# cd /opt
# ln -s /space/RMSMMT RMSMMT
# chown -h mmtuser:mmtuser RMSMMT

1-3

User Guide for the Cisco Multicast Manager 2.3.3

OL-7348-01

Chapter 1 Using the Cisco Multicast Manager

Solaris Installation Instructions

If you symbolically link /opt/RMSMMT to the actual installation directory as shown above, when
installation is complete, you must cd to the actual installation directory, similar to:

# cd /space

and issue the following command:

# chown -R mmtuser:mmtuser RMSMMT

Otherwise, the installation will create the directory and set the ownership for you.

2. If you are installing from the CDROM, enter:

# cd /cdrom/cdrom0
# ./setup.sh

(Optional) If for some reason vold is not running, you will have to manually mount the cdrom by
entering:

# mount -rt hsfs /dev/sr0 /cdrom

or

# mount -rt hsfs /dev/dsk/c0t6d0s2 /cdrom

3. If you are installing from the tar file, create a tmp directory and place the tar file in the directory:

# cd /tmp
# mkdir rms
# cd rms
# gunzip -c mmt-sol-2.1-X-full.tar.gz | tar xvf ­# ./setup.sh

You should then be able to start and stop the server by entering:

/opt/RMSMMT/S98mmt

and

/opt/RMSMMT/K98mmt

The default login is admin/rmsmmt.

Note The K98mmt script will stop the apache server and the polling daemon.

The S98mmt script will only start the apache server. You will have to manually start the polling daemon
through the application if desired.

During installation, the K98mmt script is installed in the /etc/rc0.d directory.

This will ensure that the polling daemon shuts down properly upon system reboot.

The server is configured by default to run on port 8080. If you want to change the port, edit the following
file:

/opt/RMSMMT/httpd_perl/conf/httpd.conf

Licensing

Licensing

CMM 2.3.3 requires a license file. The application license is contained in the license.key file. This file
should be placed in the following directory:

On Solaris:

/opt/RMSMMT/mmtsys/sys

On Linux:

/usr/local/netman/mmtsys/sys

The file should be owned by mmtuser (chown mmtuser:mmtuser license.key) and be set to read-only
(chmod 0444 license.key). The license is tied to the IP address of the CMM server.

Starting and Stopping CMM

To start the application:

On Solaris:

From the CMM home directory (by default, /opt/RMSMMT) run the S98mmt script.

On Linux:

From the CMM home directory (by default, /usr/local/netman) run the S98mmt script.on Linux.

To stop the application, run the K98mmt script.

The S98mmt script also runs the S98mmtpolld script, which starts the polling daemon. The S98mmtpolld
script can also be used as a watchdog script to ensure that the polling daemon is up and running. The
root crontab configuration would be:

On Solaris:

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /opt/RMSMMT/S98mmtpolld

On Linux:

*/5 * * * * /usr/local/netman/S98mmtpolld

These entries will run the script every 5 minutes.

Logging Into CMM

To access CMM, enter the IP address or the name of the server where the software is installed. For
example: http://192.168.1.9:8080. The default port of 8080 can be changed as described in the
installation instructions.

Domain Management

Using Domain Management, you can create and edit domains. A domain is a collection of multicast
routers. Multiple domains may exist, and routers can belong to multiple domains.

The first step in using the CMM is to create a domain:

Step 1 From the Multicast Manager Home page, select the Administration tool.

Step 2 Click on Domain Management.

Step 3 Click on add a new domain. The System Configuration page appears.

Step 4 Complete the fields in the System Configuration page (see field descriptions below) and click Save to

continue and create the new domain. Click Cancel to exit without creating a domain.

The System Configuration page contains:

Field Description

Management Domain A management domain is defined as a contiguous

group of PIM neighbors sharing the same SNMP
community string.

Default Read Only SNMP read-only community string.

Default Read Write SNMP read-write community string. This is

required for retrieving and validating device
configurations.

SNMP Timeout Retry period if node does not respond. Default

value is 0.8.

SNMP Retries Number of retries to contact a node before issuing

a timeout. Default value is 2.

TFTP Server TFTP server IP address. Default is the IP address

of the CMM server.

VTY Password The VTY password is required if you want to

issue show commands from the application.
Certain features, such as querying Layer 2
switches, also require this. If TACACS is being
used, then a username and password can be
supplied instead of the VTY password.

Enable Password (Not currently used.)

TACACS/RADIUS Username If you are using TACACS/RADIUS then you can

enter a username here. See VTY Password above.

Note If you enter a TACACS/RADIUS

username and password here, the
application will use these values
regardless of who is currently logged in.
Users can also enter their own username
and password when issuing show
commands.

1-10

User Guide for the Cisco Multicast Manager 2.3.3

OL-7348-01

Chapter 1 Using the Cisco Multicast Manager

Using the Administration Tool

TACACS/RADIUS Password If you are using TACACS/RADIUS then you can

enter a password here. See VTY Password above.

Note If you enter a TACACS/RADIUS

username and password here, the
application will use these values
regardless of who is currently logged in.
Users can also enter their own username
and password when issuing show
commands.

Cache TACACS Info If this box is checked, CMM will cache the

TACACS username and password until the
browser is closed. This eliminates having to enter
the username and password each time you issue a
router command from the application.

Resolve Addresses Performs DNS lookups on all sources found. The

DNS name appears alongside the IP address on
the “Show All Groups” screen. If the server is not
configured for DNS, then DO NOT check the box.
If the box is checked, you may receiver a slower
response, due to the fact that the application is
trying to resolve names. This option is not
recommended if your network contains a large
number of S,Gs.

Use SG Cache Some networks contain thousands of S,Gs.

During discovery,CMM caches all the S,Gs found
in the RPs. If this box is checked, CMM reads the
SG cache when showing lists of sources and
groups, rather then retrieving them again from the
RPs in the network. The cache is automatically
refreshed if RPs are being polled as described
later in this document (see the “RP Polling”

section on page 1-28). The cache can also be

refreshed manually by clicking the Refresh
Cache button in the Multicast Diagnostics
window (see the “Show All Groups” section on

page 1-61). This button only appears if you have

the Use SG Cache option selected. It is highly
recommended to use the SG cache option. If there
are no RPs in the domain being discovered, then
the SG cache is created by querying all the devices
that have been discovered, as would be the case in
a PIM Dense-Mode network. In this case, the SG
cache is only updated when you click the Refresh
Cache button.

Discovery

Once you have created a domain, the second step in using the CMM is to discover your network using
one of these choices, found within the Discovery menu:

• Add Router (not supported)

• Adding Layer 2 Switches to Discovery, page 1-11

• Performing Multicast Discovery, page 1-12

• Adding or Re-discovering a Single Device, page 1-14

The discovery process is multicast-specific and only finds devices that are PIM-enabled. CMM builds
a database of all found devices. Discovery adds support for multiple community strings per domain,
along with device-specific SNMP timeout and retries.

Note If any new routers or interfaces are added to the network, run discovery again so that the database is

consistent with the network topology.

A single router may also be added or rediscovered on the network. A router being added must have a
connection to a device that already exists in the database. A router that is being re-discovered is initially
removed from the database, along with any neighbors that exist in the database. The router, and its
neighbors, are then added back into the database. This option would be used if a change on a device has
caused a change in the SNMP ifIndexes.

Note When possible, the snmp ifindex persist command should be used on all devices.

Adding Layer 2 Switches to Discovery

Layer 2 switches are not included in discovery and must be added manually. You can add switches
individually, or you can import a list of switches in a csv file.

To add switches individually, enter the switch name or IP address and the community string, then click
Add.

To import a list of switches:

Step 1 Create a text file by typing:

#import file format switch IP address or switch name
# this line will be skipped
switchA

192.168.1.1
switchC

10.10.10.1

Step 2 Save the file.

Step 3 Within the Administration too, click on Discovery.

Step 4 Click Add L2 Switch. The Multicast Layer 2 Switch Configuration page appears.

Step 5

Click Browse. Open the file you created.

Step 6 Click Import.

Note Sometimes switches are deployed in a network using different SNMP community strings than those used

on the routers. In this case, simply create another domain, with the appropriate SNMP community
strings, and add the switches to this domain.

Performing Multicast Discovery

To perform a new multicast discovery:

Step 1 Within the Administration tool, click on Discovery.

Step 2 Click Multicast. The Multicast Discovery page appears.

Step 3

Next to Management Domain, select the domain you want to discover (only domains that are created
from the System Configuration window appear here). If you select a different domain from the default,
you must complete steps 1 and 2 again.

Step 4 Complete the fields in the Discover Multicast Domain pane (see field descriptions below) and click

Start Discovery to continue. As routers are discovered, they appear in the browser window.

Step 5 (Optional) To view discovery progress as it is running, click Refresh Status.

Note For details on adding or re-discovering a single device, see the “Adding or Re-discovering a

Single Device” section on page 1-14.

The Discover Multicast Domain pane of the Multicast Discovery page contains:

Field Description

Management Domain (Read-only) Lists the selected management

domain.

Seed Router Enter the IP address of the seed router to initiate

discovery from. If you enabled DNS when
configuring the domain, enter a name.

Chapter 1 Using the Cisco Multicast Manager

Using the Administration Tool

CMM discovers all routers in the network that are multicast enabled and have interfaces participating in
multicast routing. If the discovery fails to find any routers, or if there are routers in the network that you
expected to discover but did not, check the following:

• Connectivity to the routers

• SNMP community strings on the routers

• Discovery depth setting—is it sufficient

• SNMP ACLs on the routers

When discovery is complete, the browser window displays the time it took to discover the network, and
the number of devices discovered:

Discovery took 15 seconds
Discovered 5 routers

The amount of time the discovery takes depends on the number of routers, number of interfaces, and
router types.

If the discovery seems to stop at a particular router, or seems to pause, check that particular router’s
connectivity to its PIM neighbors. Also, check the PIM neighbor to see if it supports the PIM and
IPMROUTE MIBs. Again, because the discovery is multicast specific, unless these MIBs are supported,
the device will not be included in the database. Issuing the sh snmp mib command on a router gives this
information.

When discovery has finished, you can view the discovered routers in the lower left pane.

Adding or Re-discovering a Single Device

To add or re-discover a single device:

Step 1 Within the Administration tool, click on Discovery.

Step 2 Click Multicast. The Multicast Discovery page appears (see Figure 1-4).

Step 3 Within the Add/Rediscover a Single Device pane, enter the

Step 4 Next to Management Domain, select the domain you want to discover or add to (only domains that are

created from the System Configuration window appear here). If you select a different domain from the
default, you must complete steps 1 and 2 again.

Step 5 Complete the fields in the Add/Rediscover a Single Device pane (see field descriptions below) and click

Add/Rediscover to continue. As devices are discovered, they appear in the browser window.

Community Strings You can add additional community strings if

required.

Discovery Depth Number of PIM neighbors the CMM will discover

from the seed router (similar to a hop count).
