TABLE 12 TCS information
Field Description
Global cache group information
This section of the display lists global information for the cache group.
Admin-status The administrative status of the cache group. The status can be one of
the following:
• Disabled
• Enabled
Hash_info The source and destination mask for the cache distribution hash value.
The ServerIron ADX compares the website’s IP address to the hash mask
to determine to which cache server to send a request for a given website
to.
As long as the cache server is available, the ServerIron ADX always
sends requests for a given IP address to the same cache. If a cache
becomes unavailable, the ServerIron ADX directs requests for websites
normally served by that cache to the remaining cache servers until the
unavailable cache server becomes available again.
Cache Server Name The names of the cache servers in the cache group. These are the
names you assigned when you configured cache server information on
the ServerIron ADX.
Admin-status The administrative state of the cache server, which can be one of the
following:
• 1 – Enabled
• 2 – Failed
• 3 – Testing
• 4 – Suspect
• 5 – Graceful shutdown
• 6 – Active
L4-Hash-Buckets The number of hash distribution slots used by the cache server. The
ServerIron ADX has 256 hash distribution slots available. A hash
distribution slot associates a website destination IP address with a
specific cache server. Refer to “Increasing the TCS hash bucket count”
on page 60 for more information about hash values.
L7-Hash-Buckets The number of Layer 7 cache buckets.
Traffic statistics for traffic between clients and the cache
