eNSP S5700 Strange Interface Behaviour

Dear all,

           I'm writing this post to publish a bug in eNSP related to Ethernet link negotiation between switches S5700.

Given the following lab...

The GE0/0/1 of S1 has been set with no auto negotiation, Speed 10Mb/s and half-duplex. The GE0/0/1 of S2 instead is configured with no auto negotiation, Speed 100Mb/s and full-duplex. See the following configuration.

[S1-GigabitEthernet0/0/1]display this
#
interface GigabitEthernet0/0/1
 undo negotiation auto
 speed 10
 duplex half
#
return

[S2-GigabitEthernet0/0/1]display this
#
interface GigabitEthernet0/0/1
 undo negotiation auto
 speed 100
#
return


The expected behavior is that the link shouldn't go up. Instead we observe the contrary. See the following output

[S2]display interface Ethernet brief
PHY: Physical
*down: administratively down
(l): loopback
(b): BFD down
InUti/OutUti: input utility/output utility
Interface                   PHY   Auto-Neg Duplex Bandwidth  InUti OutUti Trunk
GigabitEthernet0/0/1        up    enable   half    4294967G     0%     0%    --


There are different issues:

1) Physical is up while it should be down

2) Auto-neg should be disabled according with the configuration

3) Duplex should be full

4) Bandwith value is absolutely wrong


I think these things should be fixed. Hope of being helpful.

Regards
