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.
