Are you able to post scrubbed configs for both switches?<br />
<br />
By chance do you have any type of DHCP snooping enabled? Do the vlan tags (or lack thereof) match on the link between the switches?

Dear Experts, <br />
<br />
&nbsp;I need to know why the new Cisco switch 3560 is not working with a HP 1400-sg Procurve switch. <br />
<br />
It is not allowing IP traffic dynamic (DHCP) or static (IP). &nbsp;<br />
<br />
Is there a limit on the mac addresses I need to know about? <br />
<br />
Regards, <br />
<br />

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.
