- assembly number—Part number of the module, chassis, or fan tray
- assembly rev.—Hardware revision of the module, chassis, or fan tray
- ram (MB)—Memory capacity of the host processor
- number of MAC addresses—Total number of Ethernet addresses on an I/O module or an IOA
- base MAC address—Lowest Ethernet address on an I/O module or an IOA
- Tray—Number of the fan tray in the E120 and E320 routers; 0 indicates the primary fan
- Major/Minor rev—Revision number of the module on the E120 and E320 routers
- Example 1—Displays the status of hardware on an
ERX7xx model

show utilization
- Use to display information about the resources that modules consume.
- When you issue this command, the router releases available memory on the SRP module immediately; however, the display appears a few seconds later.
- To display detailed information about the average CPU utilization percentage calculated over 5-second, 1-minute, and 5-minute intervals for each module installed in the router, use the detail keyword.
- Field descriptions
- 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.
- *** indicates that a module installed in the slot is running an incompatible version of JunosE Software.

consumed on the router

In this example, slot 12 is empty (as indicated by the --- symbol), the CPU utilization for the FE-8 module installed in slot 10 is unavailable (as indicated by the ??? symbol), and the SRP module installed in slot 7 is running an incompatible version of JunosE Software (as indicated by the *** symbol).

In this example, slots 3, 5, 12, 14, and 16 are empty (as indicated by the --- symbol), fabric slices are present on the SFM-100 modules in slots 8, 9, and 10 (also indicated by the --- symbol), the CPU utilization for the LM-4 module installed in slot 1 is unavailable (as indicated by the ??? symbol), and the SRP-100 module installed in slot 7 is running an incompatible version of JunosE Software (as indicated by the *** symbol).
