# fcping(8)

Fibre Channel Ping (ELS ECHO) tool

## NAME

fcping - Fibre Channel Ping (ELS ECHO) tool

## SYNOPSIS

**fcping** \[-fqx\] \[ -i *interval* \] \[ -c *count* \] \[ -s *size* \] -h *source* *target*

source = *interface* \| *MAC* \| *WWPN* \| *FC-ID*

target = -P *WWPN* \| -N *WWPN* \| -F *FC-ID*

## DESCRIPTION

The **fcping** command performs the Fibre Channel FC-LS-2 ECHO ELS command and displays the reply. The max payload for **fcping** is 2108 bytes. When no **-c** is given, **fcping** will continue until user interrupts.

## OPTIONS

- **-f**

  Flood ping

- **-q**

  Quiet! just print summary

- **-x**

  Hex dump of responses

- **-i** *interval*

  Wait *interval* seconds between each ping

- **-c** *count*

  Stop after sending *count* pings

- **-h** *source*

  Source is *interface* like ethX, *MAC* address, *WWPN*, or *FC-ID*

- **-s** *size*

  Byte-length of ping request payload (max 2108)

- **-F** *FC-ID*

  Destination port ID

- **-P** *WWPN*

  Destination world-wide port name

- **-N** *WWNN*

  Destination world-wide node name

## EXAMPLES

Sends ELS ECHO to Port FC-ID 0xbf0027 from interface n0.170 with max 3 pings.

```
fcping -c 3 -h n0.170 -F 0xbf0027
```

```
