Top Forums UNIX for Beginners Questions & Answers How to find the count of IP addresses that belong to different subnets and display the count? Post 303039423 by rbatte1 on Friday 4th of October 2019 10:22:59 AM

If you have them in a file, how about:-
Code:
cut -f-3 -d"." input|sort|uniq -c

Would that do? It's not quite the pretty output, but you get the detail you need.



I hope that this helps,
Robin

NAME
fipvlan - Fibre Channel over Ethernet VLAN Discovery SYNOPSIS
fipvlan [-c|--create] [-s|--start] [-m|--mode fabric|vn2vn] interfaces fipvlan -a|--auto [-c|--create] [-d|--debug] [-s|--start] [-m|--mode fabric|vn2vn] [-l|--link-retry count] fipvlan -h|--help fipvlan -v|--version DESCRIPTION
The fipvlan command performs Fibre Channel over Ethernet (FCoE) Initialization Protocol (FIP) VLAN Discovery over Ethernet interfaces. fipvlan can be used as a diagnostic tool to determine which VLANs have FCoE services available on a network, prior to configuring VLAN interfaces and the Open-FCoE initiator. fipvlan can also be used to create VLAN interfaces as they are discovered, and to start the Open-FCoE initiator. The --create and --start options are primarily intended to be used as part of an Open-FCoE boot solution. FCoE instances started in this way cannot be destroyed or reset by fcoeadm. fipvlan takes a list of network interface names to run the VLAN discovery protocol over, or the --auto option to use all available Ethernet interfaces. fipvlan will enable any interface which is found disabled. If no response is received on that interface it will be shutdown again when fipvlan terminates. OPTIONS
-a, --auto Use all Ethernet interfaces currently available -c, --create Create network interfaces for discovered FCoE VLANs. If a VLAN device already exists for a discovered VLAN, a new VLAN device will not be created. -d, --debug Enable debugging output -s, --start Start the Open-FCoE initiator on discovered FCoE VLANs -m, --mode fabric|vn2vn Specify whether VLAN discovery is performed in the default fabric mode, or in VN2VN mode. -f, --suffix suffix Append the specified string suffix to VLAN interface names. -l, --link-retry count Retry check for link up to count times. The link state is checked every 500 ms. The default number of retries is 20. -h, --help Display a help message with basic usage instructions -v, --version Display the fipvlan version string VLAN NAMING CONVENTIONS
If a new VLAN device is created, it will have the name dev.vlan; where dev is the name of the Ethernet parent device and vlan is the discovered VLAN ID number. An optional suffix may be appended to this with the the -f command line option. EXAMPLES
Display all discoverable VLANs with FCoE services fipvlan --auto Discover FCoE VLANs on interface eth2, create VLAN devices and start the Open-FCoE initiator fipvlan --create --start eth2 In this example if FCoE services were available on VLAN 101 of network interface eth2, then a VLAN interface eth2.101 would be created and used as the parent device for the initiator.
