Create a Map

Each map can have up to 32 rules associated with it. The following table lists the various rule conditions that you can select for creating a map, inclusion map, and exclusion map.

Conditions

Description

L2, L3, and L4 Filters

EtherType

The packets are filtered based on the selected ethertype. The following conditions are displayed:

■   IPv4
■   IPv6
■   ARP
■   RARP
■   Other

L3 Filters

If you choose IPv4 or IPv6, the following L3 filter conditions are displayed:

■   Protocol
■   IP Fragmentation
■   IP Time to live (TTL)
■   IP Type of Service (TOS)
■   IP Explicit Congestion Notification (ECN)
■   IP Source
■   IP Destination

L4 Filters

If you select TCP or UDP protocol, the following L4 filter conditions are displayed:

■   Port Source
■   Port Destination

MAC Source

The egress traffic matching the specified source MAC address is selected.

MAC Destination

The ingress traffic matching the specified destination MAC address is selected.

VLAN

All the traffic matching the specified IEEE 802.1q Virtual LAN tag is filtered. Specify a number from 0 to 4094.

VLAN Priority Code Point (PCP)

All the traffic matching the specified IEEE 802.1q Priority Code Point (PCP) is filtered. Specify a value between 0 to 7.

VLAN Tag Control Information (TCI)

All the traffic matching the specified VLAN TCI value is filtered. Specify the exact TCI value.

Pass All

All the packets coming from the monitored VMs are passed through the filter. When Pass All is selected, the L3 and L4 filters are disabled.

When you select a condition without source or destination specified, then both egress and ingress traffic is selected for tapping the traffic. For example, if you select EtherType as IPv4, TCP as the protocol, and do not specify IPv4 source or destination, then both egress and ingress traffic is selected for monitoring purpose.

When you select a condition with either source or destination specified, it determines the direction based on the selection.

Note:  You can create Inclusion and Exclusion Maps using all default conditions except EtherType and Pass All.

To create a new map:

1. In the Monitoring Session canvas, from Maps section, drag and drop a new map template to the workspace.
2. Click on the map, then click details. The map rules quick view is displayed.
3. Enter the appropriate information for creating a new map.

Parameter

Description

Alias

The name of the new map.

Note:  The name can contain alphanumeric characters with no spaces.

Comments

The description of the map.

Rule Conditions

Map Rules

The rules for filtering the traffic in the map.

To add a map rule:

a. Click Add a Rule.
b. Select a condition from the Search L2 Conditions drop-down list and specify a value. Based on this selection, the Search L3 Conditions drop-down list is automatically updated.
c. Select a condition from the Search L3 Conditions drop-down list and specify a value.

 
d. (Optional) If you have selected TCP or UDP as the protocol in the L3 conditions, then select Port Source or Port Destination from the Search L4 Conditions drop-down list and specify a value. If you have selected conditions other than TCP or UDP, then the Search L4 Conditions drop-down list is disabled.
e. (Optional) In the Priority and Action Set box, assign a priority and action set.
f. (Optional) In the Rule Comment box, enter a comment for the rule.

Note:  Repeat steps b through f to add more conditions. Repeat steps a through f to add nested rules.

Note:  Do not create duplicate map rules with the same priority.

4. To reuse the map, click Add to LibrarySave the map using one of the following ways:
o   Select an existing group from the Select Group list and click Save.
o   Enter a name for the new group in the New Group field and click Save.

Note:  The maps saved in the Map Library can be reused in any monitoring session created in the project.

5. Click Save.

To edit or delete a map, click a map and select Details to edit the map or Delete to delete the map.

Click the Show Targets button to view the monitoring targets highlighted in orange.
Click on to expand the Targets dialog box. Click on

Click on the Filter icon to filter Instances based on the Instance Name Prefix, IP address, or MAC address.
