Issue with LAGG interface MTU on 2.4.5-p1

jhorne

just did a fresh install of 2.4.5-p1 on a brand new dell server with intel 10g (ix0 driver). when i created a LAGG LACP interface with the 2 ix0/ix1 interfaces, the interface does not show up on the interfaces list, and i cannot changed the MTU to 9000. i was able to create all the vlans i needed with the LAGG set as parent interface, but then i receive the error that the vlan cannot have greater MTU than the parent interface. all the vlan interfaces are otherwise working properly except i cannot change their MTU due to the LAGG0 interface not appearing in the list.

i have built identical configuration in the past (older hardware, older intel 10g interfaces) but the LAGG0 shows up in the interface list and i can edit the MTU. right now i dont remember what version the original install of this older config was, but its current version was 2.4.4-p3. actually i took its duplicate system and upgraded from 2.4.4-p3 to 2.4.5-p1 and the LAGG0 interface still appears on the list.

im not sure if this is something that should be submitted as a bug? has anyone else experienced this issue with a new install of 2.4.5 yet?

Hmm, I've not been able to replicate that.

I assume you still see lagg0 in the ifconfig output?

It just doesn't show in the list or available interfaces to assign?

it actually does show up with ifconfig -a, but it does not appear in the interfaces drop down.

Can we see the ifconfig output? It must be presenting in some odd way for the gui to exclude it.

it actually looks normal to me. i can post it later, but ill have to do extensive redacts.

interestingly, the upgrade pre-2.4.5 one has this entry in its backup xml:

	<opt3>
		<descr><![CDATA[LAGG0]]></descr>
		<if>lagg0</if>
		<enable></enable>
		<spoofmac></spoofmac>
		<mtu>9000</mtu>
	</opt3>

and the new fresh install of 2.4.5 does not, but it does have all sub-interfaces for all the vlans, like this:

	<opt1>
		<descr><![CDATA[VLAN_130]]></descr>
		<if>lagg0.130</if>
		<enable></enable>
		<spoofmac></spoofmac>
		<ipaddr>redacted</ipaddr>
		<subnet>24</subnet>
	</opt1>
