slot—Slot in which the module resides
type—Type of module
heap (%)—Percentage of the RAM that is currently in use by software running on
the module
cpu (%)—Percentage of the module CPU capacity currently used; this field appears
only when the detail keyword is omitted
bw exceed—Status of bandwidth oversubscription for this slot; this field appears
only when bandwidth oversubscription is configured
Y indicates that this slot is in an oversubscribed slot group
--- indicates that no module is installed or slot has no bandwidth oversubscription
The following additional fields appear when the detail keyword is used:
last available cpu (%)—Average CPU utilization percentage for each installed
module during the last 5-second interval for which data was available. If the current
CPU utilization data for a module is not available at any point, the last available
cpu (%) field displays the last available 5-second CPU utilization percentage,
which is the same value that appears in the cpu (%) field when the detail keyword
is omitted. If the current 5-second CPU utilization data is available, the last available
cpu (%) field and the 5 sec cpu (%) field display the same value.
5 sec cpu (%)—Average CPU utilization percentage for each installed module
during the most recent 5-second interval
1 min cpu (%)—Average CPU utilization percentage for each installed module
during the most recent 1-minute interval
5 min cpu (%)—Average CPU utilization percentage for each installed module
during the most recent 5-minute interval
Depending on the output of the show utilization command when you use the detail
keyword, some or all of the following symbols and explanatory notes might appear:
--- indicates an empty slot on ERX7xx models, ERX14xx models, or the ERX310
router. For the E120 and E320 routers, this symbol indicates either an empty slot,
or a fabric slice that resides on an SRP module or on a switch fabric module (SFM).
??? indicates that the current CPU utilization data is unavailable for the specified
interval. Data might be unavailable for one or more of the following reasons:
A slot is in an inactive state.
A line module is very busy (that is, using 100 percent of its CPU capacity) and
is unable to send its CPU utilization data to the SRP module.
A line module is experiencing communication problems that prevent it from
sending its CPU utilization data to the SRP module.
