# nodel2traceroute(8) - Returns the layer 2 route through an Ethernet network managed by confluent given 2 end points.

## SYNOPSIS

`nodel2traceroute [options] <start_node> <end_noderange>`

## DESCRIPTION

**nodel2traceroute** is a command that returns the layer 2 route for the configured interfaces in nodeattrib. It can also be used with the -i and -e options to check against specific interfaces on the endpoints. If the --interface or --eface option are not used then the command will check for routes against all the defined interfaces in nodeattrib (net.\*.switch) for the nodes.

## PREREQUISITES

**nodel2traceroute** the net..switch attributes have to be set on the end points if endpoint is not a switch

## OPTIONS

- `-e` EFACE, --eface=INTERFACE interface to check against for the second end point or end points if checking against multiple nodes
- `-i` INTERFACE, --interface=INTERFACE interface to check against for the first end point
- `-c` CUMULUS, --cumulus=CUMULUS return layer 2 route through cumulus switches only
- `-h`, `--help`:  
  Show help message and exit

## EXAMPLES

- Checking route between two nodes:  
  `# nodel2traceroute n244 n1851`  
  `n244 to n1851: ['switch114']`
- Checking route from one node to multiple nodes:  
  `# nodel2traceroute n244 n1833,n1851`  
  `n244 to n1833: ['switch114', 'switch7', 'switch32', 'switch253', 'switch85', 'switch72', 'switch21', 'switch2', 'switch96', 'switch103', 'switch115']  n244 to n1851: ['switch114']`
