Chapter 24 Configuring IP Storage
Configuring Gigabit Ethernet Interfaces
PortChannel members must be one of these combinations: ports 1-2, ports 3-4, ports 5-6, or ports 7-8.
Figure 24-5 Ethernet PortChannel Scenario
In Figure 24-5 , Gigabit Ethernet ports 3 and 4 in slot 9 are aggregated into an Ethernet PortChannel.
All FCIP data traffic for one FCIP link is carried on one TCP connection. Consequently, the aggregated
bandwidth will be one Gbps for that FCIP link.
PortChannel configuration specified in also apply to Ethernet PortChannel configurations.
PortChannel interfaces provide configuration options for both Gigabit Ethernet and Fibre Channel.
However, based on the PortChannel membership, only Gigabit Ethernet parameters or Fibre Channel
parameters are applicable.
Gigabit Ethernet interfaces cannot be added to a
PortChannel if one of the following cases apply: - if the interface already has an IP address assigned, or
- if subinterfaces are configured on that interface.
Configuring CDP
The Cisco Discovery Protocol (CDP) is supported on the management Ethernet interface on the
supervisor module and the Gigabit Ethernet interface on the IPS module.
IPS Core Dumps
IPS core dumps are different from the system kernel core dumps for other modules. When the IPS
module operating system (OS) unexpectedly resets, it is sometimes useful to obtain a copy of the
memory image (called a IPS core dump) to identify the cause of the reset. Under that condition, the IPS
module sends the core dump to the supervisor module for storage. Core dumps take up significant space
and hence the level of what gets stored can be configured using one of the two options:
• Partial core dumps (default)—Each partial core dump consists of four parts (four files).
•
Full core dumps—Each full core dump consists of 75 parts (75 files). This dump cannot be saved on
the supervisor module due to its large space requirement.
