Parsers let you transform raw device outputs into structured data that NetBrain can act on. This category is for creating, sharing, and refining custom parsers

Reiterive parsing when the same command appears multiple times.

Does anyone have a solution to parse multiple lines with the same constant.  For example, it is easy to create a paragraph parser to parse both the switchport trunk allowed vlan and switchport trunk allowed vlan add commands, but it will only parse one of the switchport trunk allowed vlan add instances. The “add” option can appear a number of times under one interface.  interface GigabitEthernet7/12 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,11,19,21,194,240,400,403,413,451-454,511,552 switchport trunk allowed vlan add 660,666,667,672,711,719,725,810,820,830,832 switchport trunk allowed vlan add 833,961,965,966

Iterative Parsing inside Paragraph Parser

Description:We are creating a Paragraph parser.  There are variables we want to store inside the paragraph; however, we’re only seeing a way to store the first instance as a variable.  Here’s an example of our command output: Addresses, Flags: Is-Preferred Is-Primary        Destination: 1.2.3.4, Local: 1.2.3.4, Broadcast: Unspecified, Generation: 1      Addresses, Flags: None        Destination: Unspecified, Local: 1.2.3.4, Broadcast: Unspecified, Generation: 1      Addresses, Flags: Is-Preferred        Destination: 1.2.3.4, Local: 1.2.3.4, Broadcast: Unspecified, Generation: 1      Addresses, Flags: None        Destination: Unspecified, Local: 1.2.3.4, Broadcast: Unspecified, Generation: 1Question:Our paragraph identifier starts above with “Logical Interface”.  In output we’re sharing (above) we want to store each Address and Destinastion as a variable; however, we want them tied to that logical interface.  Would this need to be done through a script (regex compile) or can we iterate

Parser for NXOS Radius Groups

I am having issue creating a parser for NXOS radius groups.   We recently migrated from one set of radius servers to another.   I would like to be able to parse the AAA groups and pull out the group name, servers part of the group, and any particular settings.   aaa group server radius radius     server 10.1.2.3    server 10.1.2.4     deadtime 0    use-vrf default    no source-interfaceaaa group server radius Active-AAA     server 10.2.3.4    server 10.2.3.5     deadtime 0    use-vrf default    source-interface mgmt0Seems like no matter what I do the parser will only pull first svr configured.

Question with Parser/Qapp Repository

Hello everyone, we just got our Netbrain setup with API access to Meraki and Velocloud via a proxy server. I was wondering if there was a repository for parser files for API calls outside of the built in parser files.  The parser file setup for API is a bit different than the other types of parser files and I am looking for more examples. Also, if there is a repository parser files to avoid the re-inventing the wheel scenario that would be great.

Route table/RIB change log

Hello, I would like to know if it is possible to record and compare the differences in route tables over time for any router on our WAN. We use BGP so not sure if that makes any differnce as it should be just a show command and output of text from the CLI. I want to have a way to look back to see what changed on the device config (if at all) and the state of the live RIB vs the last saved/benchmarked RIB. If any of this is even possible could it be done as part of a scheduled task and some sort of alert to notify that something has changed? Thanks in advance.

How to get the complete output of Show Command to a variable retrieved by a parser ?

I would like to perform parsing programmatically. So, what I want is to get the complete output of a “show command”/”snmp query” to a parser variable. Please help.
