Oracle SBC Troubleshooting Notes

Booting

#

There are three files used in the boot process. the bootloader, the boot image, and the diagnostic image files. Files are uploaded to /code/images/. Refer to the release notes to confirm which images are compatible as a jump upgrade method maybe be needed if your software is old enough.

Boot flags enable system boot behavior(s). The user can set a single flag, or add hex digits to set multiple flags.

• 0x00000008 Bootloader ~7 seconds countdown
• 0x00000040 Autoconfigure wancom0 via DHCP enable - VM platforms only
• 0x00000080 Use TFTP protocol (instead of FTP) enable - VM platforms only
• 0x00000100 Bootloader ~1 seconds quick countdown - VM platforms only

Networking

#

Some useful commands.

• show arp used to see ip to mac bindings
  • To manually alter the table you can use arp-add or arp-delete
  • arp-check will force the SBC to reach out and attempt to add an entry. this command does not work if there is an already existing entry.
• add-hip-ip needs to be configured along with add-icmp-ip to be able to ping to and from the SBC. Multiple IP can be configured.
• Interface statuses can be checked with the following commands
  • show interface
  • show interface brief
  • show interface ethernet
• show routes Show routes relevant to management traffic, it do not show routes for signaling or media traffic.
  • host-routes can be used for sending traffic via the wancom0 interface.

System Level

#

For boot level information there are a few varieties of show version that can be used.

• show version boot Useful for getting the serial number.
• show version image Useful for getting the configured boot image.
• show version hardware Useful to pull hardware information.
• show memory usage Useful to see the consume memory or the SBC.
  • show memory application Provides more detailed application memory usage.

System Stats

#

Some useful commands for system level stats.

• show ntp status Provides info on where the SBC is synchronized to.
• show ntp server Provides detailed info on the NTP servers.
• show platform Useful to determining information about where the SBC is deployed(virtual).
  • show platform health-check Confirms if system processes are running.
  • show platform limits Used to determine the maximum number of various functions.
  • show platform cpu Provides information about the system CPU.
  • show platform cpu-load Provides information about the CPU usage.
• show processes Used to view active processes.
  • show processes <service name> Used to view information about a specific process.
  • show processes top Used to get a top like view of system cpu usage.
• show space hard-disk Used to display disk usage.

Backups

#

Display Backups

#

To display backups from the CLI

• show dir /code/bkups

Restore a backup

#

To restore a backup from a file use the following command.

• restore-backup-config <dir(is using sub dir)/filename>

ARP

#

to check the device table you can use 2 commands

• show arp
• arp-check 0 1 9 10.10.9.21
  • command <media interface slot> <media interface port> <vlan> <IP>

Basic System Checks

#

The following information can be used to do a basic assessment of the platform health.

• show platform
• show uptime
• show system-state
• show sipd agents
• show memory usage
• show buffers
• show platform health-check
• show platform cpu-load

Local Policy Routing

#

The Oracle Communications Session Border Controller applies preference to configured local policies in the following order: Reference

• Cost (cost in local policy attributes) is always given preference.
• Matching media codec (media profiles option in local policy attributes).
• Longest matching To address (to address list in local policy).
• Shortest matching To address (to address list in local policy).
• Longest matching From address (from address list in local policy).
• Shortest matching From address (from address list in local policy).
• Narrowest/strictest day of week specification (days of week option in local policy attributes).
• Narrowest/strictest time of day specification (start time and end time options in local policy attributes).
• Wildcard matches (use of an asterisk as a wildcard value for the from address and to address lists in local policy).
• Wild card matches are given the least preference. A prefix value of 6 is given a higher preference than a prefix value of * even though both prefix values are, in theory, the same length.
