Aggregated items from SNMP Template

[fratotec]

Hi,
I´m trying to create an aggregated item for the total traffic ( inOctets + outOctets ) for an Cisco Router on Zabbix 2.2.2, from the items of the SNMP Device Template.
The Itens from the template look like:
Network interfaces: Outgoing traffic on interface GigabitEthernet0/1 ifOutOctets[GigabitEthernet0/1]
the key of the original item is "ifOutOctets[{#SNMPVALUE}]".

When I try to use as function:
last("ifOutOctets[GigabitEthernet0/1]") + last("ifinOctets[GigabitEthernet0/1]") I get an "invalid key GigabitEthernet0" error.
It looks like Zabbix doesn´t like the "/" in the key name.

Any ideas to work around this, other than create aditional plain SNMP items (like ifinoctets.1 / ifoutoctets.1 ) and aggregate them ?

Thanks

Franz

My "Total traffic on $1" Item prototype configured like that:

Name: Total traffic on $1
Type: Calculated
Key: total.traffic.[{#SNMPVALUE}]
Formula: last("ifInOctets[{#SNMPVALUE}]")+last("ifOutOctets[{#SNMPVALUE}]")
Type of information: Numeric(unsigned)
Data type: Decimal
Units: bps
