I have a topology with 1 x Cisco WS-6509-E Layer 3 Switch connected to 1 x HPE FF 5700-40XG-2QSFP+ Switch and another HPE FF 5700-40XG-2QSFP+ Switch. These HPE FF 5700s are each connected to 2 x HP 5130-48G-PoE+-4SFP+ (370W) EI Switches and 1 x HP 5130-24G-4SFP+ EI Switch. The Cisco WS-6509-E has the udld aggressive command globally configured. I am trying to establish two connections running from each HP 5130 switch to each of the HP FF 5700s. I have the udld aggressive command configured globally on the Cisco WS-6509-E. On two of the HP 5130s I have the lldp compliance cdp command configured but on one I don't have it configured. When I try to make a dual connection from the switch running from the switch with lldp compliance cdp command configured, I get the link to one of the HP FF 5700 placed into err-diabled. The logs below show what happened:
Jul 15 11:08:28.682 PDT: %UDLD-SP-4-UDLD_PORT_DISABLED: UDLD disabled interface <port>, unidirectional link detected
Jul 15 11:08:28.682 PDT: %PM-SP-4-ERR_DISABLE: udld error detected on <port>, putting <port> in err-disable state
Jul 15 11:08:28.758 PDT: %PM-SPSTBY-4-ERR_DISABLE: udld error detected on <port>, putting <port> in err-disable state
Should I undo lldp compliance cdp command on the HP 5130 switches in order to get a dual connection to the HP FF 5700s?
