6. CONFIGURING THE TTE-SWITCH LAB SPACE
6.3 Downloading the Switch Configuration
Files can be downloaded from the TTE-Switch Lab Space through any TFTP client. The user therefore
has to know the preconfigured IP address.
In comparison with the upload process (where the file must be converted), a file downloaded from the TTE-
Switch Lab Space is a plain binary file without any header, hash, ECC protection, or other modification.
To upload such a file again, the prepare_tftp_file.py script needs to be run.
tftp -i <ip address > GET <target.bin > <filename.bin >
<ip address> The actual IP address of the switch (default: 10.10.10.10).
<target.bin> The target configuration file that will be downloaded, e.g.,
TTC_NetworkCfg.bin, TTC_EScfg.bin, or TTC_SWEcfg.bin.
<filename.bin> The output binary file, i.e., the file converted by prepare_tftp_file.py.
Example
The following command downloads a binary from the flash memory:
tftp -i 10.10.10.10 GET TTC_EScfg .bin ES_user_cfg. bin
6.4 Recovering from Errors
The following error conditions may apply during operation. These descriptions are for general guidance
only.
Error Possible Cause Mitigation
Firmware does not re-
spond on the network
Network cable not connected
Wrong network speed
Wrong MAC address
Firmware in ERROR mode
Wrong port configured for PHY
Check UART for critical error
Check network cable
Set network speed to 100 Mbit
Check for UART error messages
SNMP error response on
GET request
OID not supported. No mitigation.
SNMP error response on
SET request
OID not supported. No mitigation.
TFTP error response File corrupted
Wrong file name provided
See Section 6.2 on page 32 and Sec-
tion 6.3 on the current page.
See Table 6 on page 32.
SNMP trap is not trans-
mitted
User configuration is not correct. Check the current firmware mode via
SNMP.
No response to SNMP
GET requests
The firmware is in ERROR mode. Check the UART for an error message.
SNMP timeout Firmware in wrong mode
Firmware in ERROR mode
Wrong network address (default con-
figuration)
Wrong network address (user config-
uration)
Check the last message on the UART.
Check the addresses used in the user
configuration.
