Displays the current configuration for the system or the specified module.
|
module-name |
Specifies the name of configuration module. The term configuration module refers to feature in ExtremeXOS. By displaying a module, you can view the commands used to configure that feature. For example, to display all of the configurations that you made for only STP, specify the stp as the module-name. |
|
detail |
Displays configuration data including default. If the detail option is not specified, only the configuration changes you made to the factory defaults are shown. |
N/A.
If the output scrolls off the top of the screen, you can use the enable clipaging command to pause the display when the output fills the screen. The default for clipaging is enabled.
These files have the .cfg file extension. Do not use a text editor to view or modify your XML-based switch configuration files.
To save the configuration file as an ASCII-formatted file, and to view it with a text editor, see the upload configuration [hostname | ipaddress] filename {vr vr-name} and the load script filename {arg1} {arg2} ... {arg9} commands.
Beginning with ExtremeXOS 12.1, when you specify show configuration only, the switch displays configuration information for each of the switch modules excluding the default data.
You can display only the configuration of a module of interest by using the module-name keyword. For example, some of the modules are AAA, ACL, BGP, EDP, FDB, SNMP, and VLAN. Use [TAB]-completion to see a list.
You must have administrator access to view the output of the show configuration command.
Depending on the software version running on your switch, the configurations on your switch, and the type of switch you have, additional or different configuration information may appear.
The output of show configuration fdb after upgrading to ExtremeXOS 30.1 differs from 22.x output because of the changes in per VR-based IPARP and ND configurations (see examples below).
The following example shows the current configuration of the OSPF module on the switch:
# show configuration ospf # Module ospf configuration. # configure ospf routerid automatic configure ospf spf-hold-time 3 configure ospf metric-table 10M 10 100M 5 1G 4 10G 2 configure ospf lsa-batch-interval 30 configure ospf import-policy none configure ospf ase-limit 0 disable ospf originate-default disable ospf use-ip-router-alert disable ospf configure ospf restart none configure ospf restart grace-period 120 disable ospf export direct disable ospf export static disable ospf export rip disable ospf export e-bgp disable ospf export i-bgp configure ospf area 0.0.0.0 external-filter none configure ospf area 0.0.0.0 interarea-filter none
The following example illustrates the difference between ExtremeXOS 30.1 versus 22.x output for FDB.
Example 1
22.x
# show configuration fdb detail configure iparp vr VR-Default max_entries 8192 configure iparp vr VR-Mgmt max_entries 4096 configure neighbor-discovery vr VR-Default max_entries 4096 configure neighbor-discovery vr VR-Mgmt max_entries 4096
30.1 and Later
# show configuration fdb detail configure iparp max_entries 12288 ---- > Default values of (VR-Default + VR-Mgmt) = 8192 + 4096 configure neighbor-discovery max_entries 8192
Example 1
22.x
# show configuration fdb configure iparp vr VR-Default max_entries 10000 configure iparp vr VR-Default max_pending_entries 10 configure iparp vr VR-Default max_proxy_entries 10 configure iparp vr VR-Mgmt max_entries 2000 configure iparp vr VR-Mgmt max_pending_entries 20 configure iparp vr VR-Mgmt max_proxy_entries 20 configure iparp vr vr1 max_entries 3000 configure iparp vr vr1 max_pending_entries 30 configure iparp vr vr1 max_proxy_entries 30 configure neighbor-discovery vr VR-Default max_entries 10000 configure neighbor-discovery vr VR-Default max_pending_entries 100 configure neighbor-discovery vr VR-Mgmt max_entries 1000 configure neighbor-discovery vr VR-Mgmt max_pending_entries 10 configure neighbor-discovery vr vr1 max_entries 60 configure neighbor-discovery vr vr1 max_pending_entries 70
30.1 and Later
# show configuration fdb configure iparp max_entries 14096 --------- max_entries = (Configured VR-Default max_entries) + (Default VR-Mgmt max_entries) = 10000 + 4096 configure iparp max_pending_entries 266 -------- max_pending_entries = (Configured VR-Default max_pending_entries) + (Default VR-Mgmt max_ pending_entries) = 10 + 256 configure iparp max_proxy_entries 266 -------- max_proxy_entries = (Configured VR-Default max_proxy_entries) + (Default VR-Mgmt max_ proxy_entries) = 10 + 256 configure neighbor-discovery max_entries 14096 -------- max_entries = (Configured VR-Default max_entries) + (Default VR-Mgmt max_entries) = 10000 + 4096 configure neighbor-discovery max_pending_entries 1124 -------- max_pending_entries = (Configured VR-Default max_pending_entries) + (Default VR-Mgmt max_ pending_entries) = 100 + 1024
Example 1
22.x
# show configuration fdb # # Module fdb configuration. # configure iparp vr VR-Default max_entries 10000 configure iparp vr VR-Mgmt max_entries 1000 configure iparp vr vr-user1 max_entries 2000 configure iparp add 20.0.0.100 vr VR-Default 00:0a:0b:0c:0d:0e configure iparp add 10.68.13.100 vr VR-Mgmt 00:66:77:88:99:aa configure iparp add 100.0.0.150 vr vr-user 00:11:22:33:44:55
30.1 and Later
# show configuration fdb # # Module fdb configuration. # configure iparp max_entries 14096 --- max. limit of one current global table of kernel configure iparp add 20.0.0.100 vr VR-Default 00:0a:0b:0c:0d:0e --- configure iparp add 10.68.13.100 vr VR-Mgmt 00:66:77:88:99:aa | --- All static entries of all VRs are restored back as long as they do not exceed current max limit. configure iparp add 100.0.0.150 vr vr-user 00:11:22:33:44:55 --- Once they exceed the limit, rest of the entries will be discarded and logged as failures.
