H3C S7506E с супервизорами LSQ1SRP12GB и Comware 5.20 Release 6605P03 и Cisco WS-C3560G-24TS 12.2(35)SE5 ipbase.

На H3C настроил поддержку CDP согласно гайду. H3C видит Cisco, а Cisco не видит H3C. Пишет ошибку:

CDP-EV: Device ID information is missing in packet

sw001#sh cdp tr
CDP counters :
        Total packets output: 149, Input: 0
        Hdr syntax: 0, Chksum error: 0, Encaps failed: 0

На h3c у вас lldp. Соответственно на циске тоже надо настраивать lldp, а не cdp.

Как показал беглый гуглинг, по крайней мере некоторые из коммутаторов H3C умеют cdp или " CDP-compatible LLDP ".

Но его надо отдельно включать, примерно такими командами:

lldp enable
lldp compliance cdp
lldp compliance admin-status cdp txrx
