Ports G0/17 through G0/20: Connects to external ports 17 through 20, respectively:
򐂰 Preset default values for ports going to external connections (includes ports g0/17 through
g0/20, shown for port g0/17):
description extern1
switchport trunk native vlan 2
򐂰 These ports default to shutdown when in a new BladeCenter. You must use the
Management Module Web interface, under I/O tasks, Advanced settings to set External
Ports to Enabled) to bring them up the first time.
If you do not Enable these ports via the Management Module, any attempt at performing
no shutdown will result in the error message % Shutdown not allowed on this interface.
To resolve this message you must log into the Management Module and go into advanced
settings for each IGESM and set External ports to Enabled.
򐂰 Default native VLAN is set to 2.
RJ45 Service port:
򐂰 This is the traditional RJ45 serial console port found on most Cisco products:
– Default settings: 9600, N, 8, 1
– Supports speeds up to 115,200 bps
򐂰 When initially shipped, a cap plate is installed into the console port RJ45 jack that must be
removed prior to inserting a cable. The cap reduces the likelihood of someone plugging an
Ethernet cable into this port.
See “Possible issues with Hyperterm when using the console port” on page 237 for
information on a possible issue and workaround with using this port.
Default values are different from most other Cisco switches after a write
erase
As previously shown, the default interface values used by the Cisco Systems IGESM are
different from most other Cisco switches. Besides the interface defaults previously shown, the
following list shows some other non-traditional Cisco defaults in use by the Cisco Systems
IGESM:
򐂰 Default SNMP values:
– snmp-server community public RO
– snmp-server community private RW
򐂰 The default for most Cisco switches is a single VLAN (VLAN1). The Cisco Systems
IGESM has two default VLANs:
– Management - VLAN 1
– Operational - VLAN 2
As noted elsewhere in this document, the blade server ports have VLAN 1 removed by
default. This is critical to maintain isolation between the blade servers and the
management VLAN of the Cisco Systems IGESMs.
Important: The default port settings shown above are produced after a write
erase/reload on the Cisco Systems IGESM. It should be noted that using the default
int command from config term mode does not produce the results as shown, but totally
removes all configurations from the port being defaulted. Based on this difference, the
default int command should be used with caution on the Cisco Systems IGESM.
