Re: [xcat-user] Setting MTU

2017-02-21 Thread Yuan Y Bai

Hi Christopher,

In my example, "confignics -s" can configure MTU=9000 correctly:
postscripts]# lsdef bybc0607 -i
ip,nicextraparams.eth0,nicnetworks.eth0,nictypes.eth0
Object name: bybc0607
ip=10.5.106.7
nicextraparams.eth0=MTU=9000
nicnetworks.eth0=10_0_0_0-255_0_0_0
nictypes.eth0=Ethernet

Currently, confignics use nicextraparams to configure MTU value.

The MTU in network table is used in ip from DHCP.


Best Regards

Hi Christopher,

"nicextraparams.ens1f0=MTU=9000" and set the MTU of 9000 in
the networks table, then DHCP now correctly sets the MTU to be 9000;  MTU
in the networks table can configure network from DHCP.

If you want to set MTU as static, you should use
nicextraparams.ens1f0=MTU=9000 in nics table;
Currently, confignics use nicextraparams to configure static attribute in
ifcfg-*;

Subject: [xcat-user] Setting MTU



I'm trying to configure the MTU to be 9000 for Centos 7 hosts on our
internal network. I'm using xCAT 2.12.4


A way that works is to set the MTU explicitly on a network card basis -
so I do:

nicextraparams.ens1f0=MTU=9000
and add
  "confignics -s"
to the postscripts for the node.

However we have a number of different hardware types - and the internal
network card name therefore changes.

It seems cleaner to set the MTU in the MTU column of the networks table,
instead of explicitly listing each network card type. For testing, I've
removed the "nicextraparams.ens1f0=MTU=9000" and set the MTU of 9000 in
the networks table. DHCP now correctly sets the MTU to be 9000, but this
is then removed by "confignics -s" - resulting in the default of 1500
after install.

Is this an oversight on my part, or a bug in confignics, or configeth

Re: [xcat-user] Setting MTU

We are on 2.12.4.

I think my problem is that it performs as documented and works for DHCP. 
"confignics -s" however doesn't then grab the MTU.

Re: [xcat-user] Setting MTU

Hi Chris,
 
We had a contribution from the community that added support for this late last year to add support for MTU on the networks table.
https://github.com/xcat2/xcat-core/pull/1933 Looks like it was integrated in the 2.12.4 release or newer. 
 
I'm not sure which version of xCAT you are currently on, but you can take a look at that pull request and see if it satisfies your requirements.
 
Thanks,
Victor
