The MultiSwitch 700 Device View
DRAM Available:
Displays (in Kbytes) the amount of free DRAM that is not currently being used for
data storage.
SRAM Installed:
Displays the total amount of SRAM (Static Random Access Memory) that is
installed (in Mbytes). SRAM retains data as long as the CPU is powered up. Since
it does not need the constant recharging of DRAM memory, its data can be
accessed much faster. SRAM is often used to temporarily cache — or store —
frequently accessed data or instructions commonly used by the processor. SRAM
can store less data than DRAM, however, and is more expensive to manufacture.
SRAM Available:
Displays (in Kbytes) the amount of free SRAM that is not currently being used for
data storage.
NVRAM Installed:
Displays (in Kbytes) the total installed Non-volatile Random Access Memory
(NVRAM). NVRAM retains data when the device is powered down, such as the
device IP address, community table information, and so forth.
NVRAM Available:
Displays (in Bytes) the amount of free NVRAM that is not currently being used
for data storage.
Current Switch Utilization:
Displays the current load on the switch, which is based on a percentage of
maximum switching capacity of 100%.
Peak Switch Utilization:
Displays the peak percentage of switch load (based on a maximum of 100%) that
has occurred on the switch, since power-up or last reset, along with the time and
date that it occurred. This field can be administratively refreshed, as described
below.
Reset Peak Switch Utilization:
This option allows you to clear the Peak Switch Utilization field.The Peak Switch
Utilization field will refresh to display the current switch utilization, date, and
time as the new peak values (until a new peak is experienced).
1. Click on next to the Reset Peak Switch Utilization field and select Yes from
the drop down list. (The default value is No.)
2. Click Apply to reset the displayed peak switch utilization. When the window
refreshes the value in this field will return to No.
The peak switch utilization values — including percentage, date, and time —
will be refreshed to display the current values. These values will change once
a new peak is experienced (or at the next peak reset).
