IES Global Commands
Parameters mac-address — Specifies a MAC address that is used to override the default SRRP base MAC
keep-alive-interval
Syntax keep-alive-interval interval
no keep-alive-interval
Context config>service>ies>sub-if>grp-if>srrp
Description This command defines the interval between SRRP advertisement messages sent when operating in
the master state. The interval is also the basis for setting the master-down timer used to determine
when the master is no longer sending. The system uses three times the keep-alive interval to set the
timer. Every time an SRRP advertisement is seen that is better then the local priority, the timer is
reset. If the timer expires, the SRRP instance assumes that a master does not exist and initiates the
attempt to become master.
When in backup state, the SRRP instance takes the keep-alive interval of the master as represented in
the masters SRRP advertisement message. Once in master state, the SRRP instance uses its own
configured keep-alive interval.
The keep-alive-interval may be changed at anytime, but will have no effect until the SRRP instance is
in the master state.
The no form of the command restores the default interval.
Parameters
interval — Specifies the interval, in tenths of seconds, between SRRP advertisement messages sent
message-path
Syntax message-path sap-id
no message-path
Context config>service>ies>sub-if>grp-if>srrp
Description
This command defines a specific SAP for SRRP in-band messaging. A message-path SAP must be
defined prior to activating the SRRP instance. The defined SAP must exist on the SRRP instances
group IP interface for the command to succeed and cannot currently be associated with any dynamic
or static subscriber hosts. Once a group IP interface SAP has been defined as the transmission path for
SRRP Advertisement messages, it cannot be administratively shutdown, will not support static or
dynamic subscriber hosts and cannot be removed from the group IP interface.

address
Values
Any MAC address except all zeros, broadcast or multicast addresses. The offset is
expressed in normal Ethernet MAC address notation. The defined gw-mac cannot
be 00:00:00:00:00:00, ff:ff:ff:ff:ff:ff or any multicast address.
If not specified, the system uses the default SRRP gateway MAC address with the last octet
set to the 8 least significant bits of the SRRP instance ID.
when operating in the master state.
Values
1 — 100
Default 1
