Hi Giuseppe, Thanks for your help trying to find a solution to my issue. Unfortunately we can't afford such a huge investment I think we'll have to remain with our Layer 3 OSPF triangle. I still doubt about a solution with the Nexus, but I can't see how. best regards, Eric

I know that with the Nexus switches it's possible to achieve this 'distributed' etherchannel on 2 different switchs. This is possible by using VPCs. The issue I have with these VPCs is that the Nexus switchs have as minimum bandwidth 1Gb/s ports... I would like to find a device with the 'VPC' functionnality (or similar), but with lower speeds as I have in my today's WAN architecture. Thanks. Eric

Hello Giuseppe, The link B <-> C is a L2 WAN link (about 30 km); This mean there's no stack cable between the 3750 switches. Is it still possible to create an etherchannel from A to BC (see details in my 1st post hereabove)? If yes, can you tell me with which commands? Thanks, Eric

Hello, Thank you for your answers and the helpfull link. Now if I consider to upgrade the 2nd link to 100Mb/s should this be possible? If yes how? with the 3750, with Nexus or with some other appliances? best regards, Eric

hello, We currently have 3 sites (A, B, C) interconnected by a Layer 3 OSPF triangle: A <-100Mb/s-> B <-1Gb/s-> C <-40Mb/s-> A All WAN links are in fact Layer 2 WAN links. I'd like to simplify this architecture by eliminating the OSPF Layer 3 on the Layer 2 WAN links. Site A should communicate with the 2 other sites. I'd like that sites B & C should be seen as one site. This should be possible if we create a kind of 'Etherchannel' between Site A and site BC where we would regroup the physical links A <-> B and A <-> C in a logical link A<->BC. WAN links are currently interconnected on Layer 3 switches (3750G or X series) I'm not sure this is possible with this kind of switches? I have thought using the Nexus family (5K series with 2K FEXs) but there the issue to create a VPC are the L2 links (A <-> B and A <-> C are 100Mb/s and 40Mb/s connections) which are below the 1Gb/s interfaces of the Nexus switches. If anyone should have a solution to create this 'etherchannel' like link, I'm interested. Especially if we could use the 3750 series? Thanks for all who are reading this question Eric

We have upgraded our N5K to support the new 2232TM, but now we face the issue that the 8 SFP+ ports are not visible in our config: Nexus5010_1# sh fex 103 det FEX: 103 Description: 2KSRV02 state: Online FEX version: 5.0(3)N2(2a) [Switch version: 5.0(3)N2(2a)] FEX Interim version: 5.0(3)N2(2a) Switch Interim version: 5.0(3)N2(2a) Extender Model: N2K-C2232TM-10GE, Extender Serial: FOC15262P7Q Part No: 73-13626-03 Card Id: 164, Mac Addr: 30:e4:db:66:12:02, Num Macs: 64 Module Sw Gen: 21 [Switch Sw Gen: 21] post level: complete pinning-mode: static Max-links: 1 Fabric port for control traffic: Eth1/9 Fabric interface state: Po103 - Interface Up.

Do you think it's possible to access these ports by another way and configure them to allow some hosts to connect on it or is their purpose exclusively UPLINK? best regards, Eric Gillis

Hello, We have some trouble for getting up a new Nexus 2232 TM with our existing N5K (5010) with following image: n5000-uk9.5.0.2.N1.1.bin here's my N5K current config regarding the connection between N5K & N2K: version 5.0(2)N1(1) feature telnet no feature ssh cfs eth distribute feature interface-vlan feature lacp feature vpc feature lldp feature fex ... fex 103 pinning max-links 1 description "2KSRV02" ... interface port-channel103 description FEX Server 2 switchport mode fex-fabric fex associate 103 ... interface Ethernet1/9 description FEX Server 2 PO103 fex associate 103 switchport mode fex-fabric channel-group 103 interface Ethernet1/10 description FEX Server 2 PO103 fex associate 103 switchport mode fex-fabric channel-group 103 When we connect the new 2232TM nexus we got this message: Nexus5010_1# sh fex 103 det FEX: 103 Description: 2KSRV02 state: Image Download FEX version: 5.0(3)N2(1) [Switch version: 5.0(2)N1(1)] FEX Interim version: 5.0(3)N2(0.241) Switch Interim version: 5.0(2)N1(1) Module Sw Gen: 21 [Switch Sw Gen: 21] post level: complete pinning-mode: static Max-links: 1 Fabric port for control traffic: Eth1/10 Fabric interface state: Po103 - Interface Up.

This goes on repeatedly. I think there's maybe an issue with existing image on N5K that's maybe too old to recognize the Nexus 2232 TM which has been manufactured later on... Can you confirm this? I've looked for some release notes about the 2232TM without any success Thank you for any help you can provide Eric

hello, I've a NAS configured with an IAS Radius server(W2K) installed. Everything is working fine except for callback. I'm using MS-chapv1 for authentication. When I specify a callback number in the user settings in the Active Directory, I receive a "Deny Access" message. when I look further in the router debug, I see this message: RADIUS: Bad attribute (Inapplicable attribute): type 19 len 11 data 0x30323635 RADIUS: unrecognized Microsoft VSA type 10 RADIUS: no appropriate authorization type for user. Thank you already for any help... Eric Gillis
