Hello!
I am struggling to get a working link aggregation here. Any help is appreciated.
The environment have two servers connected to the switch (Dell s3048-on)
ServerA - 10Gbps link (TenGigabitEthernet 1/49)
ServerB - 4 x 1Gbps link (GigabitEthernet 1/1-1/4)
The purpose is to have ServerB communicating with ServerA (and vice-versa) with a 4Gbps bandwidth. Case one interface goes down, the bandwidth is reduced accordingly).
I've setup serverB with bonding (balance-rr) to maximize bandwidth and I am able to achieve the following:
ServerA ===> ServerB
.................1Gbps...............
ServerB ===> ServerA
.................4Gbps...............
Here are the tests:
ServerB:~$ iperf -c ServerA
------------------------------------------------------------
Client connecting to ServerA, TCP port 5001
TCP window size: 1.06 MByte (default)
------------------------------------------------------------
[ 3] local ServerB port 47267 connected with ServerA port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 4.25 GBytes 3.65 Gbits/sec
ServerB:~]# iperf -c ServerA -d
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
---------------------------------------------
---------------
Client connecting to ServerA, TCP port 5001
TCP window size: 1.06 MByte (default)
------------------------------------------------------------
[ 5] local ServerB port 47268 connected with ServerA port 5001
[ 4] local ServerB port 5001 connected with ServerA port 48860
[ ID] Interval Transfer Bandwidth
[ 5] 0.0-10.0 sec 4.24 GBytes 3.64 Gbits/sec
[ 4] 0.0-10.0 sec 1.10 GBytes 940 Mbits/sec
Both servers communicate in vlan 11 and I could get the results above with the following two configurations in the switch:
**Config1** [Communicates, but 4Gbps only one way]
GigabitEthernet ports 1/1-1/4 and port TenGigabitEthernetport 1/49 in the vlan 11.
(conf)#interface range gigabitethernet 1/1-1/4

**Config2** [Also communicates, but 4Gbps only one way]
Tryed with partial success to configure Port-channel. Created Port-channel 1 aggregating GigabitEthernet ports 1/1-1/4 and placed the Port-channel 1 in the vlan 11.

With both configuration I had no success in achieving 4Gbps speed in both direction.
I've read a bunch of pages of both the s3048-on Command Line Reference and the Service Manual, but could not get any further.....
Would it be possible to achieve the 4Gbps communication in both directions (both starting from the 10Gbps and from the 4x1Gbps servers)?
