0

0

Article ID: KB32625 KB Last Updated: 12 Apr 2018Version: 1.0
Summary:

This article explains the JDHCP relay server-group address limit on SRX platforms, which is five (5) server-group addresses.

Symptoms:

When attempting to configure six addresses under "service-group" for JDHCP relay, it returns the following error :

root@SRX# show forwarding-options
dhcp-relay {
    server-group {
        HELPER {
            1.1.1.2;
            1.1.1.3;
            1.1.1.4;
            1.1.1.5;
            1.1.1.1;
            1.1.1.6;
        }
    }
}

[edit]
root@SRX# commit
error: Check-out failed for Junos Dynamic Host Configuration Protocol process (/usr/sbin/jdhcpd) without details
error: configuration check-out failed

 

Cause:

The JDHCP relay server-group address limit on SRX platforms is hard-coded to five (5).

 

Solution:

Since the JDHCP relay server-group address limit on SRX platforms is five, do not configure more than five server-group addresses under JDHCP relay configuration.
