I would like to use 10GE DWDM SFP+ modules to connect leaf switches to spine switches in stretched fabric design. I'm planing to use 93180-EX and 9332C switches to build ACI fabric. Both switches support DWDM SFP+ with using QSA converter module. I found that 10G SFP+ can be used in multipod design (spine to IPN), in remote leaf (leaf to upstreame router). It is not clear - Is it supported for stretched fabric (leaf to spine)?    ...

I would like to use Nexus 7700 as LISP FHR for host mobility (multi hop implementation). The Nexus configuration includes many VRF, that are used as inside VRFs connected to ASA cluster. So I would like to configure the same Instance ID (IID) for all of these VRF so that site gateway xTR see them and advertise all prefixes with using single IID. When I'm entering lisp instance-id 101 on the second VRF the following message appear:   instance-ID 101 already assigned to VRF XXXXXX Is it possible to make this configuration?   ...

I have FWSM ver 3.2 (L2 multiple contexts). We get a very low performance for tftp traffic. We are implementing remote boot for PCs. TFTP server is behind the firewall. The throughput of tftp is about 0,5 - 2,5Mbps depending on the inspection of TFTP is on or off. The same file is downloaded with windows file sharing protocols 100 times faster. What are the reasons? Thanks. ... View more
