Fetching the Switchport Configuration and the Logical Interface Configuration Important Points to Remember • The SNMP should be configured in the chassis and the chassis management interface should be up with the IP address. • If a port is configured in a VLAN, the respective bit for that port will be set to 1 in the specific VLAN. • In the aggregator, all the server ports and uplink LAG 128 will be in switchport. Hence, the respective bits are set to 1. The following output is for the default VLAN. Example of dot1qVlanCurrentUntaggedPorts output snmpwalk -Os -c public -v 1 10.16.151.151 1.3.6.1.2.1.17.7.1.4.2.1.5 mib-2.17.7.1.4.2.1.5.0.1107525633 = Hex-STRING: FF FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 The last byte is free byte . The bit for LAGs starts from 43 byte. If server LAG 1 is created with server ports Te 0/6 and Te 0/7, the respective bit for the ports are unset and the bit for LAG 1 is set in default VLAN. The corresponding output will be as follows: snmpwalk -Os -c public -v 1 10.16.151.151 1.3.6.1.2.1.17.7.1.4.2.1.5 mib-2.17.7.1.4.2.1.5.0.1107525633 = Hex-STRING: F9 FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 In the above example, the 43rd byte is set to 80. The 43rd byte is for LAG IDs from 1 to 8. But, only one LAG po 1 is set as switch port. Hence, the binary bits will be 10000000. If this converted to Hexadecimal, the value will be 80. Similarly, the first byte for Te 0/1 to Te 0/8 server ports, as the 6th and 7th byte are removed from switch port, the respective bits are set to 0. In binary, the value is 11111001 and the corresponding hex decimal value is F9. In standalone mode, there are 4000 VLANs, by default. The SNMP output will display for all 4000 VLANs. To view a particular VLAN, issue the snmp query with VLAN interface ID. Dell#show interface vlan 1010 | grep "Interface index" Interface index is 1107526642 Use the output of the above command in the snmp query. snmpwalk -Os -c public -v 1 10.16.151.151 1.3.6.1.2.1.17.7.1.4.2.1.4.0.1107526642 mib-2.17.7.1.4.2.1.4.0.1107526642 = Hex-STRING: F9 FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 Simple Network Management Protocol (SNMP) 187

Fetching the Switchport Configuration and the Logical Interface
Configuration
Important Points to Remember
•
The SNMP should be configured in the chassis and the chassis management interface should be up
with the IP address.
•
If a port is configured in a VLAN, the respective bit for that port will be set to 1 in the specific VLAN.
•
In the aggregator, all the server ports and uplink LAG 128 will be in switchport. Hence, the respective
bits are set to 1.
The following output is for the default VLAN.
Example of dot1qVlanCurrentUntaggedPorts output
snmpwalk -Os -c public -v 1 10.16.151.151 1.3.6.1.2.1.17.7.1.4.2.1.5
mib-2.17.7.1.4.2.1.5.0.1107525633 = Hex-STRING:

The last byte is free byte . The bit for LAGs starts from 43 byte. If server LAG 1 is created with server ports
Te 0/6 and Te 0/7, the respective bit for the ports are unset and the bit for LAG 1 is set in default VLAN.
The corresponding output will be as follows:
snmpwalk -Os -c public -v 1 10.16.151.151 1.3.6.1.2.1.17.7.1.4.2.1.5
mib-2.17.7.1.4.2.1.5.0.1107525633 = Hex-STRING:

In the above example, the 43rd byte is set to 80. The 43rd byte is for LAG IDs from 1 to 8. But, only one
LAG po 1 is set as switch port. Hence, the binary bits will be 10000000. If this converted to Hexadecimal,
the value will be 80. Similarly, the first byte for Te 0/1 to Te 0/8 server ports, as the 6th and 7th byte are
removed from switch port, the respective bits are set to 0. In binary, the value is 11111001 and the
corresponding hex decimal value is F9.
In standalone mode, there are 4000 VLANs, by default. The SNMP output will display for all 4000 VLANs.
To view a particular VLAN, issue the
snmp query
with VLAN interface ID.
Dell#show interface vlan 1010 | grep “Interface index”
Interface index is
1107526642
Use the output of the above command in the snmp query.
snmpwalk -Os -c public -v 1 10.16.151.151
1.3.6.1.2.1.17.7.1.4.2.1.4.0.
