 In Cisco devices, the SNMP interface table can be added to NetFlow protocol flow records by including the option within the flow record configuration. The flow record defines the keys and non-key fields that will be included in the NetFlow cache entries. By specifying snmp interface as a match or collect option within a flow record, you can ensure that SNMP index information is included in each flow entry, which allows for better correlation with other SNMP data.

The ETR, or Egress Tunnel Router, in LISP (Locator/ID Separation Protocol) is responsible for publishing EID-to-RLOC (Endpoint Identifiers to Routing Locators) mappings for a site. This is part of the LISP control plane, which separates the endpoint identity namespace (EID) from the routing locator namespace (RLOC), with the ETR functioning as the component that advertises these mappings to the rest of the network, allowing for proper routing and forwarding of packets to their intended destinations.

In Cisco routers, to allow traffic from a specific source to a specific destination on a particular port, the access control list (ACL) needs to specify the source IP address, the destination IP address, and the destination port number that needs to be accessed. Since PC-1 with IP address172.16.0.2 is trying to access the web server on port 8080 at IP address 192.168.0.5, the ACL applied inbound on SW2’s G0/0 interface should permit traffic from PC-1 to reach the web server’s specific port. References: Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) training materials.

 In Cisco IOS XR, logging discriminators allow you to define a set of rules to match syslog messages based on certain criteria like severity levels or facility codes. The correct command to filter all debugging level logs with a facility code of 7 is option D, which specifies both the severity and the facility in the discriminator configuration.
