NAME

6       ocf_heartbeat_IPaddr - Manages virtual IPv4 addresses (portable
7       version)

SYNOPSIS

10       IPaddr [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

13       This script manages IP alias IP addresses It can add an IP alias, or
14       remove one.
15

SUPPORTED PARAMETERS

17       ip
18           The IPv4 address to be configured in dotted quad notation, for
19           example "192.168.1.1".
20
21           (unique, required, string, no default)
22
23       nic
24           The base network interface on which the IP address will be brought
25           online.
26
27           If left empty, the script will try and determine this from the
28           routing table.
29
30           Do NOT specify an alias interface in the form eth0:1 or anything
31           here; rather, specify the base interface only.
32
33           Prerequisite:
34
35           There must be at least one static IP address, which is not managed
36           by the cluster, assigned to the network interface.
37
38           If you can not assign any static IP address on the interface,
39           modify this kernel parameter: sysctl -w
40           net.ipv4.conf.all.promote_secondaries=1 (or per device)
41
42           (optional, string, default "eth0")
43
44       cidr_netmask
45           The netmask for the interface in CIDR format. (ie, 24), or in
46           dotted quad notation 255.255.255.0).
47
48           If unspecified, the script will also try to determine this from the
49           routing table.
50
51           (optional, string, no default)
52
53       broadcast
54           Broadcast address associated with the IP. If left empty, the script
55           will determine this from the netmask.
56
57           (optional, string, no default)
58
59       iflabel
60           You can specify an additional label for your IP address here.

62           (optional, string, no default)
63
64       lvs_support
65           Enable support for LVS Direct Routing configurations. In case a IP
66           address is stopped, only move it to the loopback device to allow
67           the local node to continue to service requests, but no longer
68           advertise it on the network.
69
70           (optional, boolean, default false)

86
87       ARP_REPEAT
88           How many gratuitous ARPs to send out when bringing up a new address
