Red Hat Bugzilla – Bug 191137
check_link_down timeout is too short
Last modified: 2014-03-16 22:59:39 EDT
Description of problem:
the check_link_down function in /etc/sysconfig/network-scripts/network-functions
is too short for our network. We are on a Cisco Catalyst 4507R and it takes
ages for the link to come up.
Version-Release number of selected component (if applicable):
Most of the time
Steps to Reproduce:
1. Configure eth0 to dhcp
2. run "ifup eth0"
Determining IP information for eth0... failed; no link present. Check cable?
Determining IP information for eth0... done.
Our temporary fix is to change
while [ $timeout -le 10 ]; do
while [ $timeout -le 20 ]; do
This file is marked as a config file so it is OK if we update, but this should
have a better default, or at least be user configurabe.
This will be fixed for RHEL 5 via the LINKDELAY parameter.
Red Hat does not currently plan to provide a resolution for this in a Red Hat
Enterprise Linux update for currently deployed systems.
With the goal of minimizing risk of change for deployed systems, and in response
to customer and partner requirements, Red Hat takes a conservative approach when
evaluating changes for inclusion in maintenance updates for currently deployed
products. The primary objectives of update releases are to enable new hardware
platform support and to resolve critical defects.
