Hub blade AHUB3-A
1 Hub blade AHUB3-A
1.1 Overview of AHUB3-AThe ATCA hub blade AHUB3-A is the main switch used for internal traffic between
nodes in a network element and, by employing its Layer 3 capability, it can also be used
for routing traffic to/from external networks.
The hub blade provides connections for two types of networks:
• Base interface (BI) switch for the network element’s internal traffic (for communica-
tion between computer nodes)
• Fabric interface (FI) switch for communicating with external networks as well as for
the network element’s internal user data communication (for example, user data
transmitted through AMC modules).
In addition, AHUB3-A provides management interfaces towards shelf manager throughthe base switch, and the hub can also can be used for distributing a reference clock
signal to other ATCA units (the signal can be either received from an external source or
it can be generated locally.

Figure 1 AHUB3-A
The hub blade is a single-slot wide blade equipped in the two hub slots (slots 8-9) in the
16-slot ATCA shelf. Two hub blades are always required in one shelf for redundancy.
Hub blades on different shelves can be chained together through front panel base inter-
face connectors. Larger configurations may require a separate, second-level Ethernet
switch, depending on the network topology.

Embedded software
3 Embedded software
3.1 U-Boot and operating systemThe Universal Bootloader (U-Boot) initializes main components of the blade like proces-
sor, memory, serial lines and other hardware. After unit startup, it starts the Wind River
Linux operating system, which resides in boot flash memory and is loaded to random
access memory (RAM). Both the primary and secondary boot flash devices on a unit
contain a copy of the U-Boot image and its environment variables.
The U-Boot version and other software packages installed on a unit can be determined
by viewing the contents of the /etc/versions file from Linux. When the software
image of the unit is upgraded, the U-Boot should be upgraded also to ensure it includes
the most current changes. When U-Boot is upgraded, the unit’s software image and the
U-Boot environment variables are reset to the factory defaults.

3.2 IPMC subsystem
3.2.1 IPMC subsystem overview
Each blade contains an Intelligent Platform Management Controller (IPMC) subsystem,
which provides the ability to monitor, query, and log system management events on the
blade. The functions of the IPMC subsystem include controlling the blade state, power
supplies, and LEDs, monitoring voltages and temperatures, logging events, and main-
taining information on the blade.
The IPMC subsystem consists of the following components:
• IPM Controller
• EEPROM
• Local voltage and temperature sensors
• Serial interfaces
• Power load control
The IPMC subsystem communicates with the shelf manager through the Intelligent
Platform Management Bus (IPMB). It also stores a Local System Event Log (SEL) and
Sensor Data Records (SDR) which can be used for troubleshooting purposes. In addi-
tion, the EEPROM contains a Field Replaceable Unit (FRU) information storage. The
user can access the information stored in the IPMC subsystem through the system
manager.

3.2.2 System event log (SEL)
The system event log (SEL) stores all IPMI events, such as hot swaps and resets. This
information can be used for troubleshooting. The SEL is stored in an EEPROM
managed by the IPM controller. The SEL can log 447 entries. When it fills up, the oldestevents are deleted. The SEL information is periodically sent to the system manager. The
user can read the local SEL through the system manager.

3.2.3 Sensor data records (SDR)
The IPMC subsystem contains sensors for monitoring the payload power, voltages, or
the general health of the field replaceable unit. The power sensors monitor all voltages
of the IPMC power supplies. An alarm is raised if one of the values exceeds the allowedrange. The temperature sensors monitor the temperature of the board and components
as well as the ambient temperature at the blade's backplane. Sensor data record may
also contain information about, for example, the state of the FRU hot swap or software
upgrade.
The user can access the sensor data record through the system manager.

3.4 Timing and synchronization software
Timing and synchronization software in AHUB3-A is responsible for controlling the
timing and synchronization of the network element. Together with a circuit block, it con-
stitutes the timing and syncronization domain.
Timing and synchronization domain is responsible for providing shelf-internal timing
signal to other units in the shelf. For synchronization between shelves, one shelf is
selected as the master shelf. Synchronization clock signal is received from an external
clock source and distributed to other units in the shelf via the synchronization clock inter-
face in the backplane, and to other shelves via the SSU/BITS interfaces in the HBRT3-
A rear transmission module. The synchronization signal (2.048 MHz) is regenerated in
the Master Clock Generator (MCG) in each hub blade. Configurations of up to three
shelves are supported.

(unit computer) serial port and Telnet connection throught the LMP Ethernet mainte-
nance port.
Accessing the blade with serial connection
Connect a serial cable between a COM port in the FEWS and the LMP serial port
in the blade front panel.
2 Start a terminal-emulation application on the FEWS with 38400 baud rate, 8 data
bits, no parity, one stop bit, and no hardware or software flow control.
3
Log into the blade.
Use the root user account to login to the blade Linux or the admin account to login tothe blade CLI.
Connecting to the blade with Telnet
Connect an Ethernet cable between the FEWS and the LMP Ethernet maintenance
port in the blade front panel.
2
Configure the FEWS to a subnet IP address 10.0.0.x (not 10.0.0.1) and set the
netmask to 255.255.255.0.
3 Connect with Telnet to the IP address 10.0.0.1.
4
Log into the blade.
Use the root user account to login to the blade Linux or the admin account to login to
the blade main CLI.

Monitoring the blade
5 Monitoring the blade
5.1 Monitoring port statisticsSummary
AHUB3-A and HBRT3-A port statistics can be monitored from the CLI. The statistics
include information on sent and received packets, different packet types and sizes, as
well as erroneous and dropped packets.
Steps
Connect to the blade and log in as admin user.
2 If you want to monitor BI port statistics
Then
Switch to the BI CLI.
Enter the following command:
base-ethernet
3
If you want to monitor FI port statistics
Then
Switch to the FI CLI.
Enter the following command:
fabric-ethernet
4
Display the port statuses.
Enter the following CLI command:
show port all
From the output you can see which ports are enabled (EKey and Admin Modes
Enabled). Statistics are only available for enabled ports.
5 Display the port statistics.
Enter the following CLI command:
show interface ethernet <domain/port>
<domain/port> must be one of the values shown in the first column of the output of
the show port all command. The domain values are interpreted as follows:
• 0 (ports in the back panel)
• 1 (ports in the front panel)
• 2 (internal ports)
• 3 (ports in the RTM)
port is a number of an enabled port in the given domain.

5.2 Enabling and configuring syslog-ng
Summary
Syslog-ng is a standard Linux service, which collects messages from different softwarecomponents and writes the output to a log file. It can be used for monitoring the blade
operation and analyzing fault situations. The module-wide syslog-ng in AHUB3-A is
disabled by default.
When syslog-ng is enabled, the messages are stored by default to the local
/var/log/messages file. However, it is not recommended to use a local file on the
RAM disk for this purpose, because large files can affect the blade operation. Therefore
it is better to configure syslog-ng to use a remote file for storing the messages.
Configuring syslog-ng
Connect to the blade and log in as root user.
2 Open the configuration file /etc/syslog-ng/syslog-ng.conf in a text editor.
3
If you want to configure the syslog-ng message destination to a remote server (recom-
mended)
Then
Add the following two lines to the configuration file.
destination d_remote { <protocol> ("<IP address>"); }
log { source(<message type>); destination (d_remote); }
You must specify the following parameters:
<protocol> specifies the protocol (either TCP or UDP) used for the remote logging.
<IP address> specifies the IP address of the remote server.
<message type> specifies the type of messages (for example s_sys for system mes-
sages) to be redirected to the remote server.
4
If you want to change the local file where the syslog-ng messages are stored
Then
Modify the line starting with ‘destination d_mesg’.
Replace /var/log/messages with the full path and name of the new file.
Further information
The syslog-ng configuration file on the remote server specifies the name and location of
the log file. The remote system’s syslog-ng service must be configured to receive remote
messages. Syslog-ng can be restarted with the following command:
sysklogd -r

6.2 Creating a backup configuration
Summary
You can create backups of AHUB3-A configuration and store them to permanentstorage. By default, the backup configuration files are stored to the /etc directory. You
can also choose to copy a backup configuration file to a TFTP server. Backup configu-
ration files can be used later, for example in fault situations, for restoring a previously
active and working configuration.
Steps
Connect to the blade and log in as admin user.
2
Create a backup configuration file.
Enter the following command:
copy system:running-config [tftp://<IP address>/<file name>]
If you use the tftp://<IP address>/<file name> parameter and enter a valid
TFTP server IP address and a file name, the configuration will be stored to the given
TFTP server.
If you do not use this parameter, the configuration file will be stored to the /etc direc-
tory.

6.4 Creating configuration scripts
Summary
The configuration of the blade can be saved as a text-formatted script file. It is possibleto generate multiple configuration scripts, upload and apply them to one or many hub
blades.
Use the show running-config command to capture the running configuration into a
script. Use the copy command to transfer the configuration script to or from the blade.
For showing the hint on scripting commands, use the script ? command. The hint
contains the most common commands:
apply Applies a configuration script to the switch.
delete Deletes a configuration script file from the switch.
import Imports a plain text configuration script file.
list Lists all configuration script files present on the switch.
show Displays the contents of a configuration script.
validate Validates the commands of a configuration script.
